problem illustration

I want to report on a glitch in Krusader when the KDE display scaling is set above 100%. When moving the focus of the current item down the file list the ghosts of the current item show up on the file items (see attachment). The problem seems to me solely depends on the scaling, with 100% scaling there is no problem.  

STEPS TO REPRODUCE
1. install krusader
2. set KDE Display Scaling to any number above 100%, say 125%
3. in krusader panel move the current focus down the file list
4. bohold

For what it's worth, there was a previous report of this issue quite a few years ago - linking here if there's anything helpful in the previous investigation: https://bugs.kde.org/show_bug.cgi?id=388420
Comment 2 Denis 2025-03-27 14:14:17 UTC
Just found out that that with Display Scaling set to 150% or 200% the problem does not occur.
