Hover this video from the bottom up multiple times:

Sometimes the blue video progress bar gets very big.
This happens only with stylo enabled: See attached video.

(bug 1377446 is not fixed, maybe in the next build)

Maybe bug 1375969 has not fixed everything?

Sometimes it bugs in grey (like that grey in the progress bar when it has already downloaded a bit more of the future).

This bug is still present.

This seems to be related to bug 1371450.  On debug build I got the same panic in bug 1371450 while moving mouse cursor up and down. Also, skipping UpdateOnlyAnimationStyles() call does not case this issue at all.

TY, this is the bug I was thinking of, but per comment 5 it sounds like Hiro is pretty sure it's related to the APZ crash. So I'd say wait for now on this one and we'll see what happens when that's fixed.

Same as bug 1371450 comment 20: Seems to be fixed in that try build.

Fixed in Nightly 56 x64 20170715100214 @ Debian Testing (Linux 4.11.0-1-amd64, Radeon RX480),
but bug 1371450 is only in autoland yet.
Maybe someone can make this a duplicate of the solving bug.
