[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

8 total crashes since march.

Comment 3

[Jamie Nicol [:jnicol]]

It is slightly curious that all the crashes are on Nightly, though multiple versions. The sample size may be too low to draw any conclusions from that, and most the crashes are 129. Sotaro, have there been any recent changes to our DirectComposition usage that are either nightly only for the past few releases, or a new change in 129?

I wonder if Bug 1899450 might be related to the problem.

GraphicsCriticalError of crash reports often has the following error. I wondered if D3D11Device may not have been working when the problem happened.
