Comment 4

[Pascal Chevrel:pascalc]

The volume of crashes in beta 71 and release 70 is sifnificant, this bug doesn't seem to have been triaged. Nils could we have sime investigation on this one please? Thanks

Comment 5

[Liz Henry (:lizzard) (relman/hg->git project)]

Too late for a fix in 70.

Comment 6

Attachment: Crash log from try

Even though it is crashing while executing a media test case, the actual crash appears to be coming from WebRender, not Media:

Comment 7

[Nils Ohlmeier [:drno]]

Even though it is crashing while executing a media test case, the actual crash appears to be coming from WebRender, not Media (see the attached crash log).

The crash signature on the other hand appears to be a super generic crash signature for a lot of things panicing in Rust code. I looked at a couple of them, but didn't find a single one related to Media code. They are either super generic, or some of them appeared to be Layout related.
