SUMMARY

After Upgrading to Plasma 6.1 Fonts became ugly.

STEPS TO REPRODUCE
1. Set Wayland Scaling to any fractional value (e.g. 150%)
2. Pay close attention to any labels within a software. Most noticeable are window decorations when a window is maximized

OBSERVED RESULT

Letters are not in a straight line and the spacing looks off. Also some letters appear wider than others, while some are way too thin and hard to read. This affects any font. IBM Plex is used in this example, but other fonts show the same behaviour.

EXPECTED RESULT

Font rendering just like in Plasma 6.0

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux 6.9.6-arch1 (Patch Level from 24.06.2024)
(available in About System)
KDE Plasma Version: 6.1.0
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION

Font rendering becomes decent again when switched to 200% scaling.
