Crash on Pixel 8 #3743

I was in the middle of typing in a message box element on a website when this crash happened. I'm not really familiar with why, but what I can say is that I've never had this happen before.

Normally, I would provide more details for a bug report but I honestly don't think I have a reproducible test case for explaining this.

Recovery from the crash was smooth, however; almost as if nothing happened.

Looks like a GPU memory corruption bug. We're unlikely to be able to do much about this.
