SUMMARY
konsole leaves small text artifacts when scaling is set to 125% on a 1080p
monitor. The artifacts look like small 1 character wide underlines. If you
refresh the window in some way like using the reset command, resize or move the
window they disappear.  This doesn't happen with 100% scaling and does not
happen in other terminal emulators like Alacritty. I also tried running konsole
with prime-run but it displayed the same symptoms.

STEPS TO REPRODUCE
1. set display to 125% scaling and 1080p resolution
2. cd to a longer path like /etc/NetworkManager
3. cd back to home 
4. press enter a few times

OBSERVED RESULT
small artifacts appear in empty spaces where text used to be

EXPECTED RESULT
konsole window is clean
