I have a dualmonitor setup running dual 23" on 1920x1080 which has the following problem:

When running any wine application (for example "wine regedit" from console) the screen flickers and the windows have artifacts like this:

Also sometimes taking a screenshot using the print key will make compiz crash (starter and all window bars/menus are gone) when an wine application is started.

I don't have the same problems on my notebook which has the same setup. Only difference is the notebook has ATI Graphics and this PC has nvidia.

This is the output of lshw -c video:

I also noticed that running xrandr from console makes the screen flicker for some seconds on this PC, which also doesn't happen on my notebook.

Removing one screen from the setup will stop the flickering and the artifacts inside the wine applications from appearing.

Does anybody have an advice what I could try to change to make this work?
