Mouse pointer lags when moving.

Mouse pointer lags when moving.

Mouse pointer lags when moving.

Hello everyone,
I'm new to Draftsight, I've just got this one problem at the moment and my mouse cursor/pointer lags when moving around the drawing, but moves at normal speed outside the drawing area. I've checked my mouse settings in control panel and every thing looks good. Any help would be appreciated.


RE: Mouse pointer lags when moving.

I don't have DraftSight on this laptop, so I can't check right now, but it might have its own cursor controls under the Tools/Options/User Preferences menu.

If not, perhaps the graphics card in your computer is not powerful enough for the drawing window operation.

RE: Mouse pointer lags when moving.


I had the same problem, and could not find a proper way to fix it.
Right now I've also another problem...when moving object they start to move in an uncontrolled
way and after that when selecting an object the handle appear far away from the object itself.

RE: Mouse pointer lags when moving.

I have exactly the same problem as george but with windows 7-64.
This problem does not manifest with windows xp 32. Any suggestions?


RE: Mouse pointer lags when moving.

I made mistake in my post before. The The message is similar to GPHESQ and not GEORGE....

RE: Mouse pointer lags when moving.

I am having a slightly different but perhaps related problem.
If I type a command, say "line", it takes a full 3 seconds before the mouse will respond to any input. Then I can proceed to pick points with only a brief in response after each click.

Oddly, if I click the "line" button, the initial pause in response is much shorter, however, the pause after each successive click is a bit longer.

This is on a Dell Precision M4500, quad core i7, less than 3 years old, still under warranty, and all drives have recently been updated to the very newest. This is running Windows 7 x64. This happened both under the previous version of DraftSight, and also I just downloaded the newest version, and it still happens.

I use AutoCAD professionally on a daily basis, and would entertain switching to DraftSight, but not at the expense of 3 seconds per command. If DraftSight is trying to lure us away from AutoCAD and entice us to move up to their higher end software, this is not the way to do it. This is the sort of thing that will make us run away from DraftSight and never look back.

Any ideas?

RE: Mouse pointer lags when moving.

I've had a lot of performance issues with DraftSight as well, the same type of "lockup" or delay you're talking about, on very basic commands too. I've been using it for a couple of years, so it's been several releases, and running on a well equipped work station. Must be a core problem with the programming code I guess.

RE: Mouse pointer lags when moving.

Hi all,

2 years of being a Draftsight user with a lot of use. however a major hard drive failure this last week has caused me to have to rebuild the whole system. Forunately had all the drawings backed up. However the new download from DS today has left me stuck. The behaviour of the mouse pointer in the graphics area renders the programme unusable now. It jerks un predictably with the movement of the mouse and detaches, plus more fundamentally nothing will show in the graphics area. I can just about get something to "select" blind and then it shows as a dashed line with blue handles. I cannot change the background colours any longer but I do note some additional icons in the tool bars.

Have Dassault made a serious error in the updates? Have they upgraded the system requirements?


RE: Mouse pointer lags when moving.

May have a partial solution to the problem. The system I have is quite basic but more than adequate to date. However the Intel G41 Chipset driver may be partly at fault. It has always served in the past. The clean new Windows 7 installation installed the standard drivers. Used Control Panel to "Update" the display drivers via the "Look Online" option. Search took about 5 minutes and new chipset driver software was downloaded.

Draftsight now operates roughly the same as it did previous to the HDD crash.


RE: Mouse pointer lags when moving.

on May 31 I have described the same problem (mouse lag)..etc The only solution that
I could find was to change the integrated graphics on the motherboard (disabling it from the bios)
to a graphic card installed in the AGP slot. No more problems....

RE: Mouse pointer lags when moving.

Try to update graphics card drivers. Worked for me.

RE: Mouse pointer lags when moving.

I had same issue with mouse lag.
Updated graphics card and now smooth sailing.
Thanks to Iksa82.

RE: Mouse pointer lags when moving.

I fixed it by changing application specific settings in my nvidia control panel, there was not an entry for draftsight, once I added it and forced the Nvidia card as the preferred graphics processor for draftsight, restarted the program, everything was smooth.

RE: Mouse pointer lags when moving.

I have a similar problem with Draftsight. After any commands when you press enter it takes 2 to 3 seconds to work.
AutoCAD on the same computer works well.
Re-install did not work.

Any suggestion?


RE: Mouse pointer lags when moving.

Still have issue on a blank drawing. Mouse tracking is awful, not even close to acceptable. Brand new Dell XPS i7 4GB RAM AMD Fire Pro V4900. All drivers up to date. Running current version of DS. Any thoughts?

RE: Mouse pointer lags when moving.

Try opening properties with right-click on Computer, then "Advanced system settings". Now you have "System Properties" dialog, choose "Advanced" tab and "Settings" button under "Performance" group. Now you have "Performance Options" dialog. In "Visual Effects" tab choose "Adjust for best appearance" radio control and click button "Apply" Now try DraftSight. If this has solved your problem then you can play with checkboxes (options) to find right combination for you.

Playing around, I have found that DraftSight needs "Use visual styles on windows and buttons" and "Enable desktop composition" options turned on.

RE: Mouse pointer lags when moving.

Active hidden items from view and go to:

C:\users(user's name)\AppData\Roaming\DraftSight

Then delete all the contents of this folder (all folders and files)

Then start again Draftsight.

The problem is solved!

Draftsight builds again all the contents of that folder, compatible with your current computer settings.

RE: Mouse pointer lags when moving.

"C:\users(user's name)\AppData\Roaming\DraftSight"

Anyone know the equivalent location in Linux? What are the file or folder names in that location?
Draftsight worked ok before but now I get mouse pointer lag when moving over a few concentric circles, severe lag when moving over dimensions on a rather simple drawing about 50-60kB size.

RE: Mouse pointer lags when moving.

@badservo : " ~/.config/DraftSight " with debian-like systems, but erasing the whole dir didn't change anything for me : mouse pointer speed is normal on classical DraftSight windows but very slow (unusable) into the CAD window.

DraftSight 2015 SP2

RE: Mouse pointer lags when moving.

The mouse cursor problem is most likely related to the version of DraftSight, probably not your Linux or Ubuntu configuration. Due to system corruption caused by a failed kernel upgrade (fixed with sudo apt-get purge linux-image-3.2.0-84-generic) I had to update to a newer version of Draftsight but found the slow mouse cursor made the program unusable. A complete uninstall of 11.2.001 and a reinstall of 11.0.450 fixed the mouse issue. 11.0.450 has some very annoying bugs but at least it is viable (as long as you are not working on anything very important). My machine utilizes a standard Intel motherboard with on-board GPU. Intel GPU based systems are the most common computers sold but some software companies have not yet realized they need to test with those types of systems.

RE: Mouse pointer lags when moving.

On Fedora 22 I fixed the slow mouse cursor problem by disabling the "Sync to VBlank" option in nvidia-settings under "OpenGL Settings"
I have nVidia TITAN by the way.

RE: Mouse pointer lags when moving.

On Ubuntu 14.04 LTS disabling the "Sync to VBlank" in OpenGL Nvidia settings also Worked for me!
Thanks focusgfx!

RE: Mouse pointer lags when moving.

11.0.450 has been disabled by Draftsight. 11.2.015 is so slow it is unusable (even with SNA enabled). So I am now using IntelliCAD again--and it will never EXPIRE.

RE: Mouse pointer lags when moving.

I can confirm the information for DraftSight for Linux.

I'm running DraftSight 2015 SP3 (the Free* version) and got that mouse lag, only on the drawing screen.

By running nvidia-settings from Terminal, going to "OpenGL Settings" and unmarking "Sync to VBlank", the mouse lag was gone.

My Linux Distro:

$ cat /etc/issue
Ubuntu 14.04.2 LTS \n \l

$ uname -a
Linux ******* 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Thanks a lot!


RE: Mouse pointer lags when moving.

I confirm this issue with ubuntu 15.04 & nvidia graphics card.

Without the sync to vblank option works fine.

Thanks a lot!!!

RE: Mouse pointer lags when moving.

I've just installed version 2015 SP3 on my laptop running Linux Mint (Ubuntu based) as the older version of Draftsight had expired and I'm getting the same problem. I'm not using NVIDIA graphics but the built in GPU.

Does anyone have any ideas on how to fix this? It's unusable at present.


RE: Mouse pointer lags when moving.

Dear Kalex and others
Many thanks for the tip. I had the same problem in Linux Mint with an Nvidia GeForce GT220 and unmarking "Sync to VBlank" option (accessed via command line "nvidia-settings" did the trick.

RE: Mouse pointer lags when moving.

Still no solution for this problem on a Linux laptop using the built in GPU? Don't the developers bother to read this forum and take note of the bugs in their system?

The Windows version works fine on the same machine but it's a pain having to switch to Windows for this one program.


RE: Mouse pointer lags when moving.

last year I abandoned the use of DraftSight.

I needed to make some drafsight plans.
I desperately sought a solution to the problem, reported the matter to DraftSight, tried disabling "Sync to VBlank" but it is only valid for NVDIA cards, and I have a ATI.

I came across a hack which is not ideal, but allowing the use drafsight without too much difficulty

before running DraftSight, simply unplug the mouse, once the program has started, plug the mouse, and there:

it works!!!!

the only thing that stopped working is the zoom with the mouse wheel, but you can zoom with the command bar or the touchpad

RE: Mouse pointer lags when moving.

Brilliant, thanks for that jyb44. it's a bit of a pain in the ar..fternoon but at least it works. Surely it should be a simple matter for the Solidworks team to fix it?


RE: Mouse pointer lags when moving.

I have had this problem as well after having to reinstall Draftsight. The suggestion to start Draftsight without the mouse plugged in partially resolved the problem but not completely. MUCH better and at least usable now.
Ubuntu 14.04 LTS on laptop using internal display.

Thank you, jyb44.


RE: Mouse pointer lags when moving.

I had the problem of the mouse pointer lags when moving, on the Debian GNU/Linux 8 (jessie) 64-bit. I managed to stop the problem opening the DraftSight from the terminal with the command:

vblank_mode=0 /opt/dassault-systemes/DraftSight/Linux/DraftSight

RE: Mouse pointer lags when moving.

This command in previous post works on Linux Mint 17.3 (Ubuntu 14.04) with integrated GPU. Thank you andrexavier.

RE: Mouse pointer lags when moving.

that don't work with a graphic card AMD,
vblank_mode only for ATI card

RE: Mouse pointer lags when moving.

Starting DraftSight with the mouse unplugged fixes the problem but the mouse wheel doesn't work after plugging it back in. There is a bit of a work-around for this if you have two mice...
  1. Start DraftSight with one mouse plugged in and the other unplugged
  2. Plug in the second mouse after DraftSight starts and use this mouse for lag-free detail work
  3. The first mouse will be laggy but the wheel will work just fine for zooming (use with your other hand)

RE: Mouse pointer lags when moving.

It seems to be fixed in the 2016 version bigsmile


RE: Mouse pointer lags when moving.

after some problems to install DraftSight 2016, it seems to work fine

RE: Mouse pointer lags when moving.

Here it is also working fine with 2016 version.bigsmile

RE: Mouse pointer lags when moving.

Unfortunately the problem persists in DS 2016. If, while in paper space, you activate a model space viewport, the lag returns worse than ever... even after you deactivate the viewport.

RE: Mouse pointer lags when moving.

What a hoary old bug.

I wish Dassault would put their 'A Team' on it.

RE: Mouse pointer lags when moving.

Same problem on Debian Testing.
I had to delete everything in ~/.config/DraftSight/, purge DraftSight and reinstall the 2016 SP0 Ubuntu .deb.
Works fine, although I lost all my settings, but I can deal with that in order to regain a functional mouse/cursor.
