Hello again, I was able to find out a little bit more.
As I wrote I experience the issue on my second computer running on Debian Testing too. However, a second user of that computer reported that she does not suffer from that right click issue. So I tried to create a test user on that second computer too and for this test user the issue did not appear neither. So, to sum up: On my Thinkpad both my main user and the fresh test user experience the right click issue. On my PC only my main user, but neither the permanent second user nor the fresh test user experienced the issue. I cannot think of any actual relevant difference. The only thing that comes to my mind is that the Thinkpad has the keyboard Neo2 configured as main layout, so I even type in the passphrase for the whole disk encryption in Neo2. The PC uses some more usual German variant. I would be very glad if you would have any suggestion what I could do to narrow down the issue a bit more. When I created the test users, I noticed that each and every time KDE complained about that the folder `~/.config/kdedefaults` was missing. I would expect that after running `adduser` or adding a new user using KDE's settings dialog KDE would be bootstrap itself. Instead, there are error messages in `.xsession-errors` and the desktop background stays black. Should I file a separate bug for this or is this behaviour already known? Best Regards Max Görner
