Webgl canvas is causing massive memory leaks on iOS 14 which may be the reason for the silent crashes and reloads. Learn more: https://developer.apple.com/forums/thread/668999
This memory leak might very well be the reason for thousands of sites crashing and randomly reloading as reported here: https://developer.apple.com/forums/thread/662251
Still no word from Apple after three month. This bug is impacting thousands of our platforms iOS users alone. Is it a webkit issue? Is there a better place to report this?
Confirmed. Safari randomly reloads pages that make use of webGL rendering without throwing any exceptions. This has been an issue since iOS 14.0.0 and is not resolved with 14.0.1
Same issue here with Safari on iOS 14.0.1
Sites making extensive use of webGL rendering randomly reload without any exceptions being thrown
We’re noticing the same random page refreshes in Safari on iPhone with web applications with embedded webGL canvas. I can confirm that this issue has been introduced with iOS 14.
