Bug #: 51344 Summary: massive corruption on RV515 Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: bugzi11.fdo.tormod@xoxy.net

This happened early May on drm-next somewhere between 4f256e8..d3029b4, and is still there in 3.5rc3 (and in current drm-next).
Things are smeared out vertically. Looks like desktop background is not corrupted. By turning off "EXABitmaps" there is less corruption.
I haven't done git bisecting, only download bisecting from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/ and v3.4-rc6-295-g4f256e8 from May 8th was good and v3.4-rc6-315-gd3029b4 from May 10th was bad. Unfortunately the build from May 9th has been deleted in the meantime so I can not narrow it down further this way. So the commits in question should be:
