Description Iyán Méndez Veiga 2024-02-17 11:32:29 UTC
SUMMARY
The text on the Help Center in Plasma 6 RC 2 looks bad. It feels like the anti-aliasing from Plasma is ignored just for this app.


STEPS TO REPRODUCE
1. Open the help center
2. Open any manual

OBSERVED RESULT
Text looks pixelated

EXPECTED RESULT
Text should use desktop settings and use anti-aliasing if it is enabled.

Can't notice issues with the font on arch source build, wayland, with or without fractional scaling --- or maybe I just have bad eyesight and can't tell the difference
