wrong rendering from swrast
Created attachment 33959 [details] same glxinfo -l as in bug #27017 Note - rendering directly to fb/vram is currently way too slow on rv280/KMS I can see for minute as demo draws itself. Composite manager speed it up .... This demo (and the others you've filed bugs against) work fine here with swrast built with 'make linux'. With this configuration, glxinfo reports: OpenGL vendor string: Brian Paul OpenGL renderer string: Mesa X11 OpenGL version string: 2.1 Mesa 7.9-devel It looks like the issue/bugs are in the libGL GLX code or something about the swrast_dri.so module. I see the same thing here using a DRI build from a couple months ago. I tried updating my DRI stuff just now but ran into a bunch of broken dependency issues. I don't have right time to investigate any further. If you need a reference sw driver, I suggest 'make linux'. Looks like the issue is related to single buffer rendering. Some of the tests take a -db flag to turn on double buffering. point-wide looks OK with that flag. Hopefully someone else can look into this.
