Created attachment 50178 [details] glxgears with colortiling turned on When turning colortiling on all OpenGL apps have garbled graphics, see glxgears screenshot. When off, everything's fine but much slower. 2D has no problems. Kernel 3.0.1 with KMS, X packages from debian wheezy. radeon-driver from mesa git-head gives the same problem (both gallium and normal version).

Please make sure you are using r600g from mesa 7.11 or git master. Please attach your dmesg output and glxinfo output.

Created attachment 50181 [details] glxinfo output from git head (7.11-devel)
Created attachment 50182 [details] dmesg output
That's an old Mesa Git snapshot, try current master or 7.11 branch.
Ok, with current mesa git head (e09b70) the problem is gone. I thought I had already tested git head but there was a build error (in EGL) that I ignored as the gallium drivers were already in lib/gallium. But I was wrong, they were from the previous build. Sorry for the noise.
