OS/Version: Linux (All)
Status: NEW

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.
