This crash is almost exclusiveley happening on the 35 train, nowadays in Aurora, it started on Nightly 20141002030202, with regression range of https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=14665b1de5ee&tochange=2399d1ae89e9 which is where D2D 1.1 was activated. It last appeared on Nightly on the 20141014030201 build which, is just the second 36.0a1 build, so the range of this signature disappearing on trunk is https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=78a4540b0a9c&tochange=54217864bae9 - I haven't checked yet if it might have moved to a different signature, but maybe we just need to uplift one of the patches in this range to Aurora.

FWIW, if I see things correctly, the only fix I see in the "fix range" that is even gfx-related is bug 966284. CCing :nical as well here, maybe he knows if that could have been an actual fix to this crash.

Tracking this while we determine the missing patch(es).

FYI, my laptop crashes a few times a day (sometimes more like 12 times a day) due to this bug. If I force-disable D2D 1.1 in about:config, though, it switches to Firefox becoming permanently unable to draw after a short while - probably when it would have crashed? There doesn't seem to be a way to recover it either. Is this a supported configuration, so I should file a bug? Or should I just assume the problem won't matter once D2D 1.1 crashes are fixed? Things used to work fine on this machine, and I haven't touched the video drivers. I have two Firefox windows open right now that are solid white and don't repaint even if I resize them or restart dwm.exe.

Bas is the goto person for D2D 1.1 issues at the moment. D2D1.1 has been desiabled on beta (I think) (In reply to K. Gadd (:kael) from comment #3) > FYI, my laptop crashes a few times a day (sometimes more like 12 times a > day) due to this bug. If I force-disable D2D 1.1 in about:config, though, it > switches to Firefox becoming permanently unable to draw after a short while Did you do it by removing D2D1.1 from the list of backends in the pref "gfx.content.azure.backends" ? This should get you back to D2D (1.0) which is pretty stable (modulo bad drivers but that doesn't seem to be your case).

I set use1_1 to false; I'll try changing the backends list instead. Thanks. If the blank window thing persists I'll file a bug.

According to about:crashes, these pre-crash stacks might be useful here: I was playing TF2's Halloween 2014 event, and as usual the video driver(?) crashed. After killing TF2 i noticed Firefox was also not repainting and using 100% of one CPU core.

As said before, something fixed this on Nightly 36 on 10/14, and due to D2D 1.1 now being disabled on Aurora 35, it's gone there as well. So let's close down this bug.
