Window "top bar" size "issue" # 4K resolution - gpu nvidia - cpu intel

I have an P330 and copied the ssd

  • put it into a P340 with nvidia GPU

~ both haven an intel i7

p340 - newer nixos version looks like:

Same sizing “issue” with applications

  • the top bar / menu is oversized

How to fix this in the configuration.nix (or in kde plasma options)?
