Every time I change a monitor setup parameter (resolution, orientation, etc.) in systemsettings5 my google-chrome browser crashes.
Unfortunately this also happens whenever I attach or detach my external monitor and also when monitor power saving mode drops in due to a period of inactivity. This leaves me with a crashing browser several times a day . Changing the OpenGL version of the compositor has no effect on this (and also no crash).

Currently, I'm running openSUSE Tumbleweed on a Thinkpad (hence always up-to-date and currently with Chrome 85.0.4168 and kwin, plasma 5.19 on Qt libs 5.15.0). With openSUSE Leap 15.1 (until recently) this has never been a problem.

What could be the cause for this?
Can someone please confirm this ()?
Is there a possible workaround I could try in this situation?

Thanks in advance!

Did you make crash reports to Chrome? Make sure you use an up-to date browser version.
FWIW: crashes with applications should be reported to these applications, ev. to the distribution if it is a distribution specific version.
