-- Information about the crash:
So I was editing something in LibreOffice writer, sometimes changing names of
files in dolphin while watching Jimmy Dore on Youtube via Firefox. Then all the
applications got ripped away.

This already happened a bit earlier today when I move the mouse to the top
right corner of the screen. Wham! All the applications are gone.

This never happened before a "dnf update" I did "this morning" of 2022-07-09,
so it has probably something to do with that.

Unfortunately I do not know which packages those were. The "dnf.log" in
/var/log is not informative enough and my script to track package updates is
currently out of commission. Just the right time.

The reporter is unsure if this crash is reproducible.
