Description kdebugs8 2025-07-14 19:10:08 UTC 
SUMMARY
So my preferred scaling is 165%, but i get graphical glitch lines with apps if that is set. 175% works no problems, but everything is just tad too big for me that way.

STEPS TO REPRODUCE
1. Set 165% scaling.
2. Open applications like dolphin and browse the filesystem.
3. See graphical glitch lines being produced.

OBSERVED RESULT
Graphical glitch lines with apps when scaling is set to 165%.

EXPECTED RESULT
No graphical glitch lines with apps.
