Hello, here's my configuration :

Dell precision m6600 quadro 4000m on archlinux 64 bits. Nvidia drivers : 313.26

I need to redraw the window to see my drawing in some cases on the model space.

In paper space (sheets) I see bugs on the viewport window, and everything goes fine when I redraw...

Don't have this problem on my desktop computer with the same system, and nvidia geforce ti

Is there any way to tweak opengl settings ?

Do you have any clue ?

Regards
