      Description

      After upgrading to Qt 5.15.1, I've noticed frequent renderer process crashes, most often happening after logging on somewhere. The easiest way I've found to reproduce this is:

      I've also gotten reports for crashes when logging into lloydsbank.com, https://myaccount.capitalone.co.uk/login and https://transferwise.com/login2/ but those are probably not as easy to reproduce.

      Stack:

      When running with --single-process, a different crash happens - not sure if those are related, so I'm going to open a separate issue for that.
