            Bug ID: 263103
           Summary: WebGL fatal error: context lost and crashes in iOS16.7
           Product: WebKit
           Version: Safari 16
          Hardware: iPhone / iPad
                OS: iOS 16
            Status: NEW

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.
