That's a bug related to fog which has been fixed upstream in git in the
meantime.

We should keep it open for now as it might be a genuine bug in
xserver-xorg-video-i810. Can you try rebuilding it with the attached
patch to see if that helps with the new kernel? Please try both versions
of libgl1-mesa-dri, as I suspect this might fix the old version but
regress the new one, requiring another fix for the latter.
