I can recreate this issue 100% of the time. I just start writer and in the document hit enter many times or control enter or open a document with many pages and then simply move the mouse cursor over the grey area between the bottom of one page and the top of the next. As soon as I do this the screen goes black for a few seconds and I end up on the login screen for my desktop environment.
I’ve tried a fresh install of Mint 20.04 with Cinnamon and Ubuntu 20.04 with Gnome and both do the exact same thing.
dmesg shows this:
traps: SHCLX11[7303] general protection fault ip:7f92cb0ec9f6 sp:7f92a2783a00 error:0 in libc-2.31.so[7f92cb0c8000+178000]
syslog shows this:

Any ideas how to fix?
