I am currently using the latest version of Ubuntu with the classic interface. Every now and then I get "holes" in my running application exposing my background. I don't quite know how I am supposed to describe the problem, so I've uploaded a screenshot of what I mean.

Is this with or without desktop effects? – Christopher Kyle Horton Jun 17 '11 at 5:43
@WarriorIn64 Without. Ubuntu Classic (no effects). – Henrik Skogmo Jun 17 '11 at 12:48

The uplaoded image is now gone, so can't verify, but it sounds exactly like the problem I have with radeon proprietary driver (fglrx). Are you by any chance using that? A work-around is to switch to another workspace and back. The free driver (xserver-xorg-video-radeon) does not exhibit this problem at all for me, but it lacks some functionality.

Another solutions is to just take a application window and brush over it, but that is not the point. I will check out the free driver option. Thank you very much! – Henrik Skogmo Jul 3 '11 at 4:03
