Description Michael Fu 2010-09-28 23:43:33 UTC
Running Compiz on SNB, some part of the screen has render flaws.

To be fixed in 7.9.1
Comment 1 Eric Anholt 2010-10-06 17:41:47 UTC
This needs details.  With wobbly windows, window movement, and whatever produces desktop transitions (but not desktop cube), the only issue I've found is that when dragging a window to provoke desktop transition the transition is black instead of something expected (like the flip of the screen that happens if I control-alt-left/right)
Comment 2 Gordon Jin 2010-10-13 01:35:02 UTC
I confirm with Eric's observation.
