Created attachment 465759 [details] MacOS process monitor console log output The problem is observed with OffscreenCanvas only under iOS. I'm using iOS 16.4. After a few draws Safari crash and restarts itself. This is not observed with canvas element.
Thank you for the report! The attached log filtered on MobileSafari only tells us that the com.apple.WebKit.WebContent process crashed, nothing more. Could you please provide a reproducible test case? And if that's not possible, a crash log and console log filtered on WebContent could help.

The case is inking, after a few seconds input rendering crash happens. Reproducible test case is not very easy to provide. Are this logs helps?
This log may be helpful in addition to a crash log, but probably not on its own. Please see https://developer.apple.com/documentation/xcode/acquiring-crash-reports-and-diagnostic-logs We don't have to use a minimized test; any steps that reproduce this on a public website, or on a website that you can share with us in private, would work.
I know about Analytics data but it doesn't provide any information about what happens. I'll have working example tomorrow, I'll share it when is accessible.
You can access the sample on https://willtech.wacom.com/ink-canvas Draw constantly 2-3 times for a few seconds and browser will crash.
We're crashing due to running out of memory in the WebContent process. Tested locally, and this is a duplicate of 253927. *** This bug has been marked as a duplicate of bug 253927 ***
