Another kde6 problem: display is shifted after login

[juniper]

I see others are having kde 6 problems.

As the title says. What's happening is that the display is shifted slightly to the left, so that the left side of the display is at around the 80% mark measured from the left side of the screen. The screen works, the mouse wraps, but of course this is annoying.

The problem can be fixed by going to settings -> display and changing the frequency to something else and then changing it back to the standard setting, but of course this is an annoying fix.

I was having other kde 6 problems so I wiped all my settings, this shouldn't be a clash of old kde 5 config files clashing with kde 6 (if I wiped all config files correctly, which is not a trivial task).
