Created attachment 17109 [details] screenshot with RENDER enabled This problem occurs since approx. 24 hours, after a recompile of all xorg components from git. I am not exactly sure which component caused it. If I disable the render extension, the corruption is getting less. When switching to XAA it is completely gone. See the two screenshots attached.

If you're also using drm Git, then I think this is due to one of Jérôme Glissé's recent commits. I don't think that's an architecture specific problem.
