here is the screenshot of instrumenting that iphone

it is quite easy to reproduce, just to find a html5 heavy page, e.g. youtube or some html5 games, and then keep on refreshing.

the memory usage will go up to 1g, and then webkit crashes due to out-of-memory.

while I cannot reproduce this on older ios version from 13.3. the memory will not grow that fast.

I want to know if there is any memory "optimization" or restriction after ios 13.4?

btw, I have tried the latest ios 13.5.1, same crash happens.

Please file an issue using Feedback Assistant.

Pick one website (URL).
Reproduce the issue with Instruments attached.
Create a Feedback Assistant issue with the exact URL you used; the type of device (iPad or iPhone; specific model is best); and the Instruments trace.

Thanks!

Thanks! It would be great if you're able to test on iOS 14 as well (on the same/similar hardware if possible), and report those findings in FB7742515 as well.

I would love to but I can't connect Instrument to iOS14 beta, maybe need to wait xcode update.
I can tell my observation here. the problem still exists on iOS14 beta, but a bit harder to trigger it.
