There are 12 crashes (from 1 installation) in nightly 91 with buildid 20210603094827. In analyzing the backtrace, the regression may have been introduced by patch [1] to fix bug 1713544.

Severity: -- → S2
Flags: needinfo?(gwatson)
Regressed by: 1713544

This will ensure that when we re-land bug #1713544, it contains
a fix for an assertion failure that occurs when two transforms
are complex, but combined result in a 2d transform that we can
handle as a compositor surface.
