Description Pavel 2012-12-17 16:33:13 UTC 
Black areas appear when I resize windows with themes differ from Oxygen enabled. Especially annoying it becomes with transparent themes. Video is attached in URL
It seems to happen with AMD graphic cards only. I used differend ones: from HD3650 to HD7470(notebooks) with different drivers - from Catalyst 12.4 to 12.11.

Reproducible: Always
Comment 1 Thomas Lübking 2012-12-17 17:31:54 UTC 
Is this just bug #305020 - ie. depending on direct rendering invocation as well?

Please post/attach the output of

Added the qtbus support information
Comment 4 Martin Flöser 2012-12-29 08:06:53 UTC 
the output is form running with KWIN_DIRECT_GL=1. Is the problem gone when doing so and can you please attach the support information when not using the environment variable?

I can't actually. I'm betting you may check out these video corruptions with any notebooks with AMD HD Radeon cards and the proprietary driver installed. When I use free driver KDE works properly, so the solution seems to come from AMD. I've already reported this bug to their bugzilla.
