We are servicing html5 games. I got a report from a user, and I heard that it will be whited out shortly after entering the game lobby in ios 15 beta. It was not a problem in iOS 14, but in iOS 15 beta2, it is forcibly terminated shortly after entering the lobby. Safari and WKWebview are all the same, and the same problem occurs regardless of the device. The devices I tested were ipad mini4, iphone 11, iphone 12.

Seeing that it does not crash when the light effect tween is turned off, I think that the amount of memory available to the GPU for rendering has decreased.

Does anyone have similar symptoms related to html5 games?

try to disable option "GPU Process: Canvas Rendering". we don't know why it's on by default on beta 4 and 5.

Same issue occurred on both Safari & WKWebview of iOS 16.0.3 in Oct 2022.

On speicific iPhone models (tested on iPhone 12/13/SE 2020), when "GPU Process DOM Rendering" (previously GPU Process: Canvas Rendering), under [Settings] > [Safari] > [Advanced] > [Experimental Features] is ON, my website ran extremely slow and crashed very often. Also, webfonts, images and icons were not loaded properly. In the meantime, parts of the page blacked out occasionally without reason. However, iPhone XR seems not be affected.

Same issue in Webkit Webview. Please FIX this :( Or at least add some kind of way to turn it off for the webview in an xcode application.
