Description Martin Schaaf 2009-02-05 12:34:42 UTC

Intel Corporation Mobile 945GM/GMS, 943/940GML

GL apps show through overlaying windows, show flicker boxes from underlying elements and gl content moves with window but lets old content on old place.

I run compiz on ubuntu 8.10. I did not have the problems on another computer with the same xorg but an nvidia graphics card and compiz running.

Please see the attached video it shows this all.

I can confirm this issue.

- Linux runs in 64 bit mode.
- Composition manager is Metacity.
- Artifacts appear on initial mapping of the GLX window and when other windows covered by the window are modified.

Sounds like bug#8732.

Ok, what to verify this. Which software components do I have to update?
Which kernel version, which version of the X server, what else?

I don't think so. Because this report isn't only about the layering. It is also about artifacts from applications that are behind opengl windows. Like you can see in the video.

DRI2 must be enabled for any hope of correct compositing with GL.
