Created attachment 443342 [details] ios15.0.2 regression example Repro app: https://8w.8thwall.app/camera-freeze-01/ On iPhone 12 (ios14.3): Expected behavior (working), camera feed is shown with the model in view. On iPhoneXR (ios15.0.2) Regression (not working), camera feed is frozen, while the texture still is in view. Alternatively, sometimes the page is reloaded (likely due to running out of memory. Potentially similar issue: https://bugs.webkit.org/show_bug.cgi?id=232122) Reproduced the regression with both WebGL 1/2 with both WebGL via metal on/off (ios15.0.2)

The work was competed in the set of dependent bugs. This will be resolved in an upcoming iOS 15.4 Beta.
