A very strange graphic problem with Axis

[Dave89]

Hi, i'm Dave a Catia user with 7 year of experience.
For the first time i have a problem that i never seen i cannot resolve, i had try literally everything.
I don't know if someone of you can help me, but i'll try to ask.
The problem is as simple as it is annoying. the axis is hidden (maybe is most correct to say "covered") by the solid.
I draw and extrude casual line to show you.

Someone can help me? is a setting? a driver problem?

Thank you.

P.s.
i'm apologize for my english, it's not my language. i've do my best.

turn z-buffer off in catia options.

Tools, options, display, visualization,
Depth display.

Uncheck display all elements using z-buffer depth.

Thank you, really thank you. There is always something to learn, always.
Maybe the new 2k monitor aren't compatible with this option. i tell to my colleague as soon is possible.
