https://bugs.freedesktop.org/show_bug.cgi?id=53490 Bug #: 53490 Summary: [bisected] bump map corruption from kernel 3.5 Classification: Unclassified Product: Mesa Version: 7.11 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: joeri@xxxxxxxxxx Created attachment 65540 --> https://bugs.freedesktop.org/attachment.cgi?id=65540 Portal 2 screenshot - good After updating my Linux kernel to 3.5.0 I'm seeing bump map corruption in Portal 2. See attachments. I bisected it down to commit 416a2bd274566a6f607a271f524b2dc0b84d9106 - drm/radeon: fixup tiling group size and backendmap on r6xx-r9xx (v4) My GPU is a Radeon HD 5670 (Evergreen, Redwood) and I'm using Gallium (for R600) on Gentoo Linux AMD64. If I disable bump mapping in Portal 2 (command "mat_bumpmap 0") the corruption goes away, but obviously the walls and objects appear flatter. Mesa, libdrm, xf86-video-ati or Wine versions don't seem to matter. I tested some combinations of Mesa 7.11.2 and 8.0.4, libdrm 2.4.27, 2.4.33 and 2.4.38, xf86-video-ati 6.14.4 and 6.14.6, Wine 1.5.9 and 1.5.10. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
