I've confirmed it is compiz: last time it happened, disabling then re-
enabling compiz didn't fix the problem, but killing compiz did:
1. I disabled compiz
2. I killed both the compiz-decorator processes that I found with the 'ps xa |
grep compiz' command
3. I re-enabled compiz
After
I suspect the problem is a compiz/nvidia issue with two screens. I
normally have the following setup:
* laptop monitor - 1680x1050 - screen 1
* external monitor - 1680x1050 - screen 2
* wine is set to emulate a virtual desktop and CoD4 is set to run at 1680x1050.
I usually run it on screen 2.
