5 years ago I faced the same issue in all the laptops (1 Toshiba and a slew of ThinkPads) on which I have been using Lumina in the last 2.5 years.
One of the side effects for me (also consistent across laptops) is the abnormal behaviour of an auto-hide bottom panel (going all the way down with the cursor triggers the panel briefly then it disappears, as if the trigger zone was not extending fully to the bottom of the display).
I have long since turned to using xrandr to set my displays. For example:
xrandr --size 4480x1440 --output eDP-1 --mode 2560x1440 --primary --output HDMI-2 --mode 1920x1080 --right-of eDP-1
or
xrandr --size 6400x1440 --output HDMI-2 --mode 1920x1080 --primary --output eDP-1 --mode 2560x1440 --left-of HDMI-2 --output DP-1 --mode 1920x1080 --right-of HDMI-2

With two 4k screens, putting them in a rough vertical arrangement with the mouse and then using only the buttons for positioning, there is what I estimate is a 1 pixl overlap of the monitors. The only reason I noticed is that my screen saver only works on one screen. Sometimes the top overlaps the bottom, sometimes the bottom overlaps the top.
In retesting this, if I click apply a few times it will continue to increase by 1pxl until it hits a few pixels in size. However at some point it stops increasing the overlap and if continued eventually crashed almost everything. Panel was gone, browsers were gone, lte was gone, lumina-fm was gone. Right clicking on the desktop did nothing, fluxbox was gone as the two renaming programs had no window dressing. The only graphical programs to survive was VLC and Telegram. That makes absolutely zero sense... but i'm mentioning it anyway.
