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. Screenshot
Dock (cairo-dock) seems to be unaffected: Screenshot
I 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 : nvidia
Version : 302.17-1
URL : http://www.nvidia.com/
Licenses : custom
Depends On : linux>=3.4 linux<3.5 nvidia-utils=302.17
Conflicts With : nvidia-96xx nvidia-173xx
Architecture : x86_64
Description : 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.
