Description Mark Kazakov 2023-12-11 07:55:52 PST

Hi, 
We have an application that uses WebGL to present 3D models inside a WKWebView. 
Since iOS 17 we are experiencing freezes for some models that work perfectly fine on iOS 16. 

I can reproduce the issue on any iOS 17 physical device - phones and tablets.
On simulators works fine.

Thanks!

Most notably: if you can add a reproduction as the .html sources that would be runnable with Safari, that would be the most helpful.
