Yes, that definitely also happened.

Yes, we used gnome 3. It was mostly a boring default Fedora 36 
Workstation installation.

Good to hear Hans already reproduced the issue at the mentioned 
hackerspace, I assume with the exact same hardware.

I don't remember all the details though, and that laptop has found a 
new home by now. But I guess only the barcode scanner and the software 
actually matter, and we still have those.
