Yesterday we have seen this on our products, which are using the PIXI framework, and also on other various websites using WebGL.
Safari minimzed and restored can't start WebGL context on iOS 17 public release.
Also when the phone is locked and unlocked again. Does not happen always, but very often.
Happens on various phones like iPhone 11, 12, 13. Refreshing web page does NOT help. Killing Safari and restarting fixes it.
This is very critical for us.

Issue still persists after iOS patches. Updating to iOS 17.2 still did not help. WebGL stops working and refreshing the page does not help.
