Comment 77 for bug 303697

I'm also affected by the bug described by laysan_a at #26: all objects on the desktop (widgets, icons etc.) are tearing heavily. I'm on Lucid. Had same issue on Karmic. There is no Compiz or compositing activated. It's a Radeon HD 3200 (780 chipset onboard video). I regularly try the newer Catalyst releases as well as what Ubuntu pushes through "hardware drivers" but so far no luck.

Interestingly enough, in fullscreen OpenGL applications there's no tearing, only on the desktop. And the tearing also stops while glxgears is running on the screen.
