Bug Description
I used Hardy Heron, but previous versions exhibit the problem too.
Intel video adapter
Howto reproduce: start any OpenGL application under compiz (ie Desktop Effects enabled). With any mouse click, window flickers once.
When you move a window, it leaves unrefreshed area.
I understand OpenGL applications don't work well on intel cards because those don't support redirected OpenGL rendering (for example redering to texture etc), but I tried metacity compositor. It is far from perfect, but at least I don't get the 2 issues mentioned in the bug title. Maybe these can be fixed for compiz too as metacity shows it's possible?

Confirming this, easily reproduced when watching a video or running glxgears.
