Our WebGL games made by Unity encountered serious problem in iOS 16.7/16.7.1. Open the game in iOS Safari, switch to the background for a few minutes and then come back again, the problem will reappear with a high probability. Once this error occurs, the entire game will freeze with a white screen.

The similar issue of iOS 17 has been mentioned before(https://bugs.webkit.org/show_bug.cgi?id=262610), but this problem also exists in 16.7/16.7.1. There are many users using this version of the system. I hope it can be solved.

This problem is fatal and greatly affects the use of iOS safari to render WebGL game applications. Hope you can solve it in iOS 16.

Thank you for the feedback. This is still a duplicate of bug 261313 as far as WebKit open source project is concerned; deciding whether to do something about iOS 16 is outside the scope.
