X window dumps were too big to attach you can see them here - www.andyqos.ukfsn.org/screen/exa-gears3.xwd www.andyqos.ukfsn.org/screen/exa-gears2.xwd (In reply to comment #1) > X window dumps were too big to attach you can see them here - They can be trivially converted to e.g. .pngs of less than 50K. I think this is more likely an issue in one of the drivers than in the EXA core, but let's see... Does Option "RenderAccel" "off" or "EXAOptimizeMigration" "off" help?

Before I updated to current xorg git, both radeon and radeonhd (current git versions but built in xorg git tree from June) were OK.

Although mesa was an older version as well as xorg. Bug 20037 could explain this, please try the fix referenced there.

Unfortunately I have a R600 card in the box now, so can't test until the Mesa/DRI work currently ongoing is available. |

Created attachment 19980 [details] xorg log Built xorg/mesa/drm from git on 30/10/08 and have a rendering problem. Using radeon driver from git, the problem does not happen with XAA. Happens with metacity or twm - no desktop is installed. X window dumps attached. exa-gears3.xwd shows what happens to an xterm run below a glxgears window. The contents of the window are OK until it gets focus. If focus is then moved to another xterm, then that also has rendering problems as shown in exa-gears2.xwd Last working tree was git from June, attempts to bisect back from current just hit build errors. Xorg.0.log also attached.
