Description Anthony Ricaud 2021-10-03 15:47:37 PDT 
Steps to reproduce:
1. Go to any page with a video in it (example https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video)
2. Play the video
3. Click the fullscreen control
4. Crash :(

This is 100% reproducible on my machine.

I'm on a MacBook Air M1, on the Monterey Beta (21A5534d) and STP Release 133 (Safari 15.4, WebKit 17613.1.2.2). This has been going on for a couple of STP versions but I forgot to write down when it started.

We've been unable to reproduce this so far. Could you by any chance isolate this any further? E.g does this happen with extensions disabled? Are you using multiple displays, and if so, does it happen with only the built in display?
Comment 4 Simon Fraser (smfr) 2021-10-03 19:55:55 PDT 
I believe STP is trying to use a symbol that is not present in 21A5534d.
Comment 5 Alexey Proskuryakov 2021-10-03 22:25:46 PDT 
Ah yes. WebKit needs a runtime check for it.
Comment 6 Anthony Ricaud 2021-10-04 03:22:33 PDT 
I can reproduce it with extensions disabled, with one and multiple displays (built-in or external)
Comment 7 Anthony Ricaud 2021-10-18 12:32:02 PDT 
Seems like it is fixed in the Monterey RC.
