The root cause is the same as Bug 480171, which has been investigated there and
found to be a limitation in the upstream wayland protocol. It turns out
unfortunately to be a somewhat complicated issue. Anyway, marking as a
duplicate.

I don't think this is a duplicate. While the same sort of coordinate system
conversion is the most likely root cause, Xwayland scaling doesn't go through
fractional-scale-v1, so this can be fixed.

Bug 480171 isn't the one about XWayland.

Interesting thing to note is that everything is perfectly fine if you go and
change scaling from 100% to anything in a live session.  
It's upon session start where additional 1px appears - it seems like when it
tries to recalc screen size from local configs it has slightly different algo
rather that calculating screen size from env vars during session run.

I can reproduce this bug in 5.27, but not in Plasma 6. So this is already fixed
:)
