This is hitting an assert in UiCompositorControllerChild for a IPDL error.

Randall, you're the author of the assert, do you know if we need to be crashing for this?

It was copied from here:
https://searchfox.org/mozilla-central/rev/4606c7974a68cab416c038acaedcae49eed93822/gfx/layers/ipc/CompositorManagerChild.cpp#235

Which seems to have changed so it can probably be updated to match.

I'll try and take this.

Attachment: Bug 1553136 - Match CompositorManagerChild::ProcessingError behavior in UiCompositorControllerChild. r?rbarker

This will make this site only crash in debug, nightly, or dev edition builds.

[Ryan VanderMeulen [:RyanVM]]

Do we need to backport this for Beta for GV68?

Comment 8

[Ryan Hunt [:rhunt] (on leave until early May)]

I don't think this is an important fix? There's only a couple crashes with it. It would be a pretty easy uplift though (just a couple lines), so I'm not sure.

[Ryan VanderMeulen [:RyanVM]]

Any thoughts on this, Chris?

Any thoughts on this, Chris?

The crash volume is very low, so I don't think we need to uplift to GV 68 Beta.
