See attachment for an example.

All Nightly builds in-between are crashing when trying the STR.

Then I took a shot in the dark regarding bisecting m-i and luckily came to this range:

Comment 1

[Andreas Gal :gal]

Thanks for bisecting this!

Comment 2

[Milan Sreckovic [:milan] (needinfo for best results)]

Bas, let's track this as we aim to enable OMTC by default.

Comment 3

[Milan Sreckovic [:milan] (needinfo for best results)]

Just to track it in one place; we've seen the "squares problem" on particular hardware before, even with main thread compositing (e.g., bug 864472, bug 837489), so this may be just a better trigger for it.

Comment 4

[Bas Schouten (:bas.schouten)]

I believe this was fixed by some of the other patches we had recently, could we confirm this?

Comment 5

[Bas Schouten (:bas.schouten)]

I assume this was fixed as I got no response on this.

Comment 6

[Elbart]

Probably fixed by bug 1013759.
