I have recently started using Arch with nvidia driver (I had a lot of problems getting nouveau to even work so I decided to try nvidia) and I started experiencing rather odd problems. Every now and then, at random, the screen starts displaying grid over all windows.ScreenshotDock (cairo-dock) seems to be unaffected:ScreenshotI am running Arch 3.4.3-1 (x86_64) with Compiz-Fusion and Cairo-Dock under Gnome 3.4.1. Nvidia was installed using nvidia package in [extra]Name           : nvidiaVersion        : 302.17-1URL            : http://www.nvidia.com/Licenses       : customDepends On     : linux>=3.4  linux<3.5  nvidia-utils=302.17Conflicts With : nvidia-96xx  nvidia-173xxArchitecture   : x86_64Description    : NVIDIA drivers for linux.Window manager is Emerald. Graphics card is GT220.There is nothing relevant in the log (that I can see). The only way (that I found) to solve this is restart X server. I would appreciate any help - I have been trying to find any way to solve this but haven't had any luck.EDIT: I have been using gnome-shell for past 45 minutes and it hasn't crashed yet. Could it be a problem with compiz/emerald? EDIT: Nope, sadly gnome shell experiences the issue as well. However it turns out that youtube videos are unaffected.EDIT: Downgrading to 295.59 seems to have solved the problem.
