Description alex 2023-04-26 08:56:00 PDT 
Whenever a getContext has been called with either webgl or webgl2, it's no longer possible to construct a VideoFrame using the canvas

https://jsfiddle.net/jck4Lz7h/

Fails with:

[Error] InvalidStateError: Canvas has no frame
	VideoFrame (_display:121)
	Global Code (_display:121)

tested on a tot build (bf6ce950bacc83f9fb3dc35b9c1a632146d71047)

Thank you for the report! Could you please confirm when you last saw this working? I get the same error with Safari 16.5 beta.

Not sure if it was working before, I got it also in the stable version (Version 16.4 (18615.1.26.11.23))
