Description Öyvind Saether 2011-01-06 06:48:02 UTC

All windows appear without any content when desktop effects are enabled. It is possible to resize windows to make the content appear, but that snapshot of content is not updated until the window is resized again.

Kwin 4.5.95 is the rc2 of the upcoming KDE 4.6.

This new kwin appears to work perfectly (after 10 minutes of testing) with r600 classic, so this does appear to be a r600g bug. Old 4.5.x kwin works fine with both.

Please let me know if I can probide any additional information which may help resolve this bug.

The bug is also posted in the KDE bugzilla, where much more information is provided. 
The bug there was closed as UPSTREAM.

The bug you linked to is a different bug that only applies to older versions of Mesa.

I believe this is happening because we decided to try disabling strict binding by default for some drivers (including R600G) in the KDE 4.6 RC's, and this has stopped working with Gallium drivers in Mesa 7.10.

This regression should be fixed by Mesa commit 71b889f904fcba4fbc5aafff4cb62a7201f38075.
