As long as I use desktop normally (chat, browser, konsole) everything is
*almost fine. When I start any OpenGL application (not only glxgears), screen
starts to flicker.

I've created some poor quality movie to show what happens. If better quality is
needed, please let me know. I'll borrow some video camera then.

[*] almost fine = screen flickers very rarely, once for a few minutes
