Created attachment 28984 [details] video demonstrating the problem Video is attach and also available here: http://info.openanswers.org/downloads/intel-graphics-bug-in-luz-studio.ogv I think this began with the update to Ubuntu Jaunty. This was not affected by the recent fix for Atunnel (which looks fine now).
We'll need all the information in http://intellinuxgraphics.org/how_to_report_bug.html
This is on a Thinkpad T61 with integrated intel graphics and Ubuntu 9.04. xorg.conf currently has the following (added in attempt to fix graphics performance regressions from Ubuntu 8.10, not sure if they're still necessary or relevant): Section "Device" Identifier "Configured Video Device" Option "EXAOptimizeMigration" "true" Option "MigrationHeuristic" "greedy" EndSection $ lspci | grep Graphics 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) $ pkg-config --modversion libdrm 2.4.5 $ uname -m i686 $ uname -r 2.6.28-15-generic

Part of the question is how exactly do I reproduce the problem so I can work on it? Or will it be obvious? There are no packages for luz on debian at this point, so I haven't gone playing with it yet ;) (oh, and clear NEEDINFO when answering)
(got the information to reproduce, now just need to isolate a testcase)
would a minimal Luz set work as a test case?

Now that apitrace exists, making minimal testcases is a lot easier -- if you can get the bug to show up in a trace, it makes things much more tractable. We're not doing much on 965gm these days, though.
Please create an apitrace that can reproduce the issue.
