I get a blank window when launching Firefox on 10.6. Resizing the window turns it black. This is with an old Intel GMA 950 Mac mini on 10.6.8. I get a warning in the console from gfx/gl/GLContextProviderCGL.mm, line 290 (”Couldn’t init gGlobalContext”) followed by a bunch of ”invalid pixel format” and ”invalid context” messages. I could be wrong here, but my guess is that this is caused by some(?) of the patches in bug 996266. I don't know anything about that code, but I backed out to revision 201927 and that fixed the issue for me.

These sequential revision numbers are different on m-c as compared to the integration branches. Can you post the hash part of the rev, and mark this bug as blocking the relevant bug that regressed this? Thanks!

Revision 201927:a2a10e38f42d is what I backed out to. That revision is the revision just before 201928:fdd2bb040eb6 which is the first changset from bug 996266 (which this bug depends on). Note that I haven't isolated the relevant changeset, but my guess is that this regressed by bug 996266 (the console message is from GLContextProviderCGL.mm). I usually access the machine remotely and I can't build on that machine. Testing on the 10.6.8 machine involves building on another machine/packaging and then moving the .dmg to the 10.6.8 machine, but I'll see if I can isolate a specific changeset.

Turns out I was wrong about the cause of this. The last good nightly I've found was built from https://hg.mozilla.org/mozilla-central/rev/d697d649c765 which looks it was after the patches in bug 996266 landed.
No longer depends on: 996266
tinderbox builds: https://hg.mozilla.org/mozilla-central/rev/d728b2f31c56 = OK https://hg.mozilla.org/mozilla-central/rev/11e4f1678eab = Not OK Which does indicates that this could be a dupe of bug 1061209...
(In reply to Stefan [:stefanh] from comment #4) > Which does indicates that this could be a dupe of bug 1061209... Yes it is - backing out the patch in bug 994541 made the problem go away.
