I'm backported from 878a3c37d36142a192bdf5b6bfcf920832f431d7

I was following since before 36eb1cdc5fcc9a93dc4b7a62393b11522c71, then
have variously updated through:

69dc4987cbe5fe70ae1c2a08906d431d53cdd242
b5dc608c98d929abbf2fe932ed07b3c868d83342
878a3c37d36142a192bdf5b6bfcf920832f431d7

I had hopes from the sound of the bug, that
878a3c37d36142a192bdf5b6bfcf920832f431d7 would fix it, but it did not
appear to, nor did reverting (adjusting for a conflict) commit 9af90d19f
which the above commit addressed an issue with.

Mesa I have libgl1-mesa-dev	        7.10.0+git20101020.28990043-0ubuntu0sarvatt
2D   I have xserver-xorg-video-intel	2:2.12.902+git20101018.a1c54f69-0ubuntu0sarvatt
