Example 1

For months now I have this weird font rendering bugs in plasma.
Now I found out, it only happens with 150% and 155% scaling, not with 145% and 160%.
150% is just the sweet spot for me, and with 145% its not as sharp I think

As far as I can tell the bug only appears in plasma-apps like the settings, a lot in discover, the start-menu, etc. Never in the browser or other installed apps.

I did reinstall Fedora 40 and it is still there. I also can confirm, that I know a friend with Tuxedo OS and the same vertical alignment problem there. Sometimes its just that the letters are not aligned, sometimes the font is really messed up and hard to read.
