Description Michal Svoboda 2010-07-22 08:10:24 UTC

Version:           unspecified (using Devel) 
OS:                Linux

When I activate the present windows effect the window contents gets messy - some windows are upside down plus some are somewhat cropped. When a window is selected and the effect ends everything returns to normal. Other effects (desktop grid, wobbly windows) work well without this distortion.



Reproducible: Always

It also seems that the alt tab box switch effect draws the windows upside down.

Comment 2 Thomas Lübking 2010-07-22 15:15:17 UTC

don't knwo whether it's already supported in rc2, but add a blacklist entry for Lanczos and your driver string (as reported by glxinfo, see comment #7)
also post the successfull string
