the score of running "glmark2 --off-screen":
mesa 10.2: 1412
mesa 10.3 or master: 979
Through bisect, I found the bad commit is:
commit 2f28a0dc23165123cf1e8b5942acad37878edd8a
Author: Kristian Høgsberg <<a href="mailto:krh@bitplanet.net">krh@bitplanet.net</a>>
Date: Mon Jul 7 16:44:58 2014 -0700
i965: Implement fast color clears using meta operations
I did the following test to confirm this regression is introduced by commit
2f28a0d
1) git checkout 2f28a0d
git revert 2f28a0d
the score is 1412
2) git checkout 2f28a0d
git am 14c1a2a9
the score is 1052</pre>
