This issue is similar with Bug 20821
Comment 3 Ian Romanick 2011-07-25 10:54:43 UTC
Is this a regression?  Does this bug also occur on Mesa master or just the 7.11 branch?  Why is the version field set to 7.10?
Comment 4 Ian Romanick 2011-07-25 11:36:07 UTC
Resetting the component to Drivers/DRI/i915 because that's the driver Pineview uses.

Setting the version to git because the bug exists there.  I believe this bug has always existed on i915.  I have verified that it exists at least as far back as Mesa 7.10.2.
