Description Hanno Böck 2009-07-10 01:44:00 UTC 
On my intel card, GL apps in fullscreen just show a black screen with current git or 2.7.99.901. Works with 2.7.1.

I'll try to bisect this one.

Comment 4 Hanno Böck 2009-07-10 10:53:27 UTC 
bisecting failed, I stepped over compile problems with inbetween versions. I attached reg_dumper output with a fullscreen app and a log with debugging. Hope this helps.
Comment 5 Gordon Jin 2009-07-21 19:17:29 UTC 
Maybe this is because 2.7.1 uses EXA by default and 2.7.99.x uses UXA by default. How about if you set AccelMethod UXA in xorg.conf with 2.7.1?

What's the mesa version? Can you try mesa 7.5?
Comment 6 Hanno Böck 2009-08-12 11:31:57 UTC 
This got fixed somewhere between 2.7.99.902 and 2.8.0.
