Hi, after upgrade mesa-git chromium starts looking like garbage. I've tested this on polaris and i965(haswell) and only radeon is infected kernel - 4.9 or 4.10-drm-next-wip mesa - from git llvm - r291295 ddx - amdgpu-git

8b5749f65ac434961308ccb579fb8a816e4f29d5 is the first bad commit commit 8b5749f65ac434961308ccb579fb8a816e4f29d5 Author: Kenneth Graunke kenneth@whitecape.org Date: Sun Nov 15 04:37:50 2015 -0800

glsl: Override the # of varying slots for ClipDistance and TessLevel*.

Right now, this shouldn't have any effect, as all drivers use LowerClipDist and LowerTessFactors to turn the float[] arrays into vectors.

However, it should help make it possible for drivers to avoid that lowering. me is the only issue for now Signed-off-by: Kenneth Graunke kenneth@whitecape.org Reviewed-by: Jason Ekstrand jason@jlekstrand.net Reviewed-by: Timothy Arceri timothy.arceri@collabora.com
