Happened while scrolling a YouTube video page (in theater mode), on an late 2013 rMBP with integrated Iris graphics.
Socorro mentions bug 1442921 as related, but since that was fixed months ago, I assumed this was worth filing.
This is probably the same as bug 1501518. The fix is already on autoland.
Depends on: 1501518
There are 50 crashes (from 15 installations) in nightly 65 with buildid 20181024100114. In analyzing the backtrace, the regression may have been introduced by patch [1] to fix bug 1501319.

I asked the sheriffs to merge the fix and spin another nightly so hopefully you'll be able to update to a non-crashing build soon.
Blocks: wr-stability
OS: Mac OS X → All
Priority: -- → P1
The nightly channel should have a build with the fix now. Can you update and retest?
Flags: needinfo?(dirkjan)
It happened with fullscreen videos on YouTube and is fixed with 20181024133237.
When I tried earlier, I wasn't able to reproduce this deterministically (in fact, I didn't reproduce it even once after the initial crash), so not sure I can help here.
Flags: needinfo?(dirkjan)
Ok, seems like it should be safe to mark fixed. If anybody hits it again please let us know.
