3D view display

I have a Nvidia graphic card Asus GT630 4 Go Vram and I uploaded my nvidia driver with the new recommended official 352.79 release and CUDA 7.5 last development release. And not problem, when I use the GPU calculations, all is ok!

BUT here is the screen capture:

I see this horrible moire, even in edit mode.
I have a IIyama Prolite GE2488HS 1920 x 1080 60Hz so a good screen!

What is the problem, please? :mad:

Thanks in advance for all answers.

Could you send a uncropped screenshot? This doesn’t show enough info.

In any case, it looks like z-fighting: Check that you don’t have more than 1 cube at that location, or that the cube doesn’t have duplicated faces.
