Description Jaime Perea 2024-03-01 08:59:46 UTC 
SUMMARY

 Tested while running in wayland, in X11 it renders much better

As mentioned there

QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor

Allow me to watch my emails again with nice font rendering. BTW I don't know what I am doing. It seems that it's a workaround

Notice that QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor doesn't solve the issue. The main issue is that the selected font in the configuration isn't used. In KMail, if you go to Configuration / Configure KMail / Appearance / Font  and select "Message text", in Plasma 5, you could change the displayed message font and size. In Plasma 6, you can't, it simply ignored.

The only thing you can change is, in General tab, the minimum size for the font used
