I've found, and fixed, a rather nasty bug in the OpenGL driver in which some textures would be all white, some of the time. I'm a bit confused about where to report a bug, since there is a "bug reports" forum channel as well as a bug tracker on SourceForge. I opened a ticket on SourceForge, but I thought I'd post it here too, in case people don't actively check the tracker. A patch with test case is attached to the tracker.

Yes, everything correct. Best bug reports have both a tracker ticket and a forum thread. I'll look into this, didn't check the bug report yet.

Sorry to bump this, but did anybody look at it? I filed a fairly detailed bug report with a complete patch and test case almost two months ago, so I don't think it would be too much work to accept it.

Well, I have not only looked at it, but also worked through the whole code of the patch and the driver parts around. Since it reworks some important parts of the engine, it takes a little longer to integrate this change properly. But at least I could reproduce the problem, and I also understood the problematic parts of the driver already. Now it's time for the clean up and the fix will go into the engine.
