Hello,

my problem ist that the font size on the desktop, in system applications (e.g. SystemSettings, Dolphin, Kate, Ksnip, ...) but also in some 3rd-party applications (e.g. Gimp, LibreOffice) is too small on my 1920x1080 monitor while some 3rd party applications like Firefox, Chromium, Thunderbird render the fonts in the usual size. See here (the green areas are fine, the red are too small): https://i.postimg.cc/nhSnwMwP/ksnip-20210114-135025.png

I say "usual", because this problem only appeared after updating from Kubuntu 18.04 to 20.04.
I have tried increasing the font size in the system settings, but then the fonts in Firefox, Chromium, Thunderbird are too big while all the other applications would now be fine.

Any help to make the fonts the same size again would be greatly appreciated!
Regards,
Valentin
