Description Bernhard Rosenkraenzer 2009-09-22 11:44:44 UTC
With the Intel driver from current Mesa 7.6 branch on a Q35 (8086:29b2), some items incorrectly become transparent - for example, the background shines through the mountain walls and the logo in the startup screen in extremetuxracer (http://extremetuxracer.com/) 0.50.

Mesa 7.5.1 works ok on the same machine; the same snapshot of the Mesa 7.6 branch works ok with ATI graphics cards.

Sorry I don't have idea on this. Is it possible for you to git-bisect to find the regression commit?
Comment 2 Eric Anholt 2009-10-07 12:14:35 UTC
I don't see the issue, but debian unstable is currently on etracer 0.4 and I guess I'll need to get that updated.

A bisect would still be the most useful thing to do here.

I've finally had a bit of time to look at this -- turns out the problem only happens if Mesa is being built with the gallium DRI state tracker.
Comment 4 Eric Anholt 2009-12-10 17:10:04 UTC
Sorry, what exactly is the difference between the builds for success/failure?
Comment 5 Eric Anholt 2010-01-06 11:14:56 UTC
sounds like this report might have been using the unsupported gallium driver?  Closing unless you can reproduce the problem with Mesa master.
