Graphical glitch

SUMMARY
Konsole shows black horizontal lines after the color of a row changed
(scrolling selector in Midnight Commander). See gif.

- Fresh Debian 12 install.
- Does always happen - sometimes the glitch is not there. 

Tests with X11/Wayland and scaling:
- It seems like it does not happen in Wayland with 100% screen scaling.
- It happens, but looks different in Wayland at 125% scaling.
- It happens in X11 regardless of scaling.

STEPS TO REPRODUCE
1. Open mc in konsole
2. Scroll the highlighted row up or down

OBSERVED RESULT
Black bars appear, see attachment.

EXPECTED RESULT
No graphical glitch.
