--- Comment #5 from Rahim sb56637@gmail.com 2009-01-06 16:41:43 --- Hi again,
I tried glxgears, and it doesn't cause any strange symptoms. The Win32 apps that I run are not graphics programs or games that run full screen. Even Notepad and winecfg cause the flashing effect when they load. To be more precise, I was using Wine 1.1.9 on Ubuntu 8.04 and this bug did not exist. I have since upgraded both my OS and Wine to the most current versions.
Thanks for looking into this.
