--- Comment #6 from Dmitry Timoshkov dmitry@codeweavers.com 2008-02-12 08:30:50 --- Please do not PASTE logs and back traces, (attach them instead).
The log shows that Wine just queries resolution modes supported by a driver, nothing more. It does it twice though, for notepad and explorer, but that's perfectly fine.
If a simple query makes your screen flicker, that's a bug either in your display driver, or perhaps a side effect of compiz.
Does the screen flicker when you run 'xrandr' in a terminal window?
