> I can't attach a backtrace because I'm currently on GNOME (sorry I know)
Sure you can! :) The `coredumpctl` tool will show backtraces no matter which DE you're currently using. Can you use it to get a backtrace and attach it? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl

I have been trying to reproduce this after a fresh install of Arch on my machine, and I cannot for the life of me reproduce it. It likely got fixed in the hundreds of kwin fixes in 5.24. Sorry. I'll report back with a backtrace if I ever reproduce it.
