.png screenshot of Dolphin after plugging the docking station
SUMMARY
I have a dell XPS13 laptop with a 4k screen, so I configured the scaling at
200%
Then I have an external 4k monitor plugged to a USB-c docking station, at 200%
scaling also.
Plugging/unplugging the docking station creates artifacts in the display of the
KDE apps.
STEPS TO REPRODUCE
1. Open some KDE apps on the laptop, e.g. Dolphin, Konsole, Kate
2. Close the LID to suspend
3. Plug the USB-c docking station (with the LID closed)
OBSERVED RESULT
On the external monitor, these KDE apps display their content only on the
top-left quarter of their window with a 100% scaling
EXPECTED RESULT
These KDE apps should display on their whole window at 200% scaling.
