Description Shawn Starr 2009-04-28 15:12:34 UTC 
When trying to use kwin composite effects, I get massive window corruption 

See video: http://www.sh0n.net/spstarr/corrupt-composite.ogv

Windows go grey, and window contents are not visible, sometimes visible when dragging.

compiz however, has no problems.

I'm not really able to provide much for debug other than the video for the result of corruption seen. It remains to be seen if this is a driver bug or a kwin bug.

When changing product/component, please also select 'Reassign bug to default assignee and QA contact, and add Default CC of selected component'.
Comment 2 Henning Fleddermann 2009-05-22 22:11:03 UTC 
This also happens for me.
I was told in #radeon that this would be fixed as of this http://cgit.freedesktop.org/xorg/xserver/commit/?id=f250eea2e90fc50bec5214c2f41132b95edc2c46 Xorg Server commit, but it is still broken for me (using Xorg-Server git master). I also tried reseting to f250eea2e90fc50bec5214c2f41132b95edc2c46 but that does not change anything, so it is not a regression. 
Additional information: Gentoo ~amd64, Xorg-Server git, glisse's radeon-gem-cs3 branch, mesa radeon-rewrite branch, libdrm modesetting-gem branch.

Mass version move, cvs -> git

This is long gone, it works.
