The brightness of the gear faces varies periodically as the gears rotate. I think this problem started to appear around the same time as #36282, but I'm not sure. This affects both r300g and llvmpipe. May be unrelated, but this is printed to the console: Mesa: User error: GL_INVALID_OPERATION in glSampleMapATI(outsideShader) Some other mesa demos have rendering errors, too. I think those are related, and most of them are correct with mesa 7.10.2. Should I add them here, or open separate reports?
Also seen it when running in indirect rendering.
almos, either your libGL or the drivers were messed up during compilation or you have non-matching versions thereof (like an old libGL and a new driver). Delete and recompile everything. It's very unlikely that Mesa couldn't run glxgears.

Now I tried all combinations. The color of the faces of the gears are the following (copied from OOo Calc, cell separator is ';'): with shared glapi;; ;system libGL (7.10.2);compiled libGL (LD_LIBRARY_PATH=/home/almos/sources/mesa/lib/) r300g;linear shift between normal color and darker, periodically;alternate between the dark color and a different one (red gear is yellow, blue is white, green is cyan) llvmpipe;linear shift between normal color and darker, periodically;always white ;; without shared glapi;; ;system libGL (7.10.2);compiled libGL (LD_LIBRARY_PATH=/home/almos/sources/mesa/lib/) r300g;linear shift between normal color and darker, periodically;correct rendering llvmpipe;linear shift between normal color and darker, periodically;correct rendering The other demos I mentioned in the initial report are geartrain and gloss. Both render correctly, when gears does.
This is likely a duplicate of bug #36282 which is fixed now.
I tried all combinations again with current mesa, and gears is rendered correctly in each case.
