Here is a more professional report about the issue: https://bugs.archlinux.org/task/41045 (In reply to Ukyoi D from comment #1) > Here is a more professional report about the issue: > https://bugs.archlinux.org/task/41045 It appears this works with UXA, which might interest Chris. However, it's still a kernel regression. If you have the chance to bisect between 3.14 and 3.15 that might be the fastest way of tracking this down. Or try drm-intel-nightly branch of http://cgit.freedesktop.org/drm-intel.

Or try > drm-intel-nightly branch of http://cgit.freedesktop.org/drm-intel. On my laptop (Thinkpad X200) it just falls back to XRender when using Kernel 3.16. As far as I know, the only way to workaround it is to use an older kernel.
