This appears to be a NULL pointer dereference in angle code. The earliest crash on file seems to have happened after bug 1717151 landed. Jeff, can you have a look please? I'm not setting this bug as a regression of bug 1717151 just yet because I'm not 100% positive it is.

Note all the crashes seem related to streaming video. Manu crashes happened on Twitch and the rest on other streaming platforms.

This is new in 94. Mixed hardware, windows 10 and 7, currently the #9 top crash in beta according to crash telemetry.

Might be related to the angle update? Jeff, any ideas?

Yeah, definitely could be.

The only direct change to the file that the crash is in was benign, but that's not as exonerating as if there was no change there.
