Multiple distros appeared to have the same issue, so I considered this as an issue Plasma.

Now I'm using Manjaro.

Hardware: NVidia Geforce GTX 1080

Command used to install the driver:

Code: Select all

sudo mhwd -a pci nonfree 0300

I don't know what I messed up, and this phenomenon appeared to multiple distros, including Kubuntu, openSUSE and Manjaro KDE.

How can I solve this? And what additional info should I attach?

EDIT: Solved most problems by forcing font DPI, however, the login screen is still huge.

The issue is not with Plasma, it is the Nvidia driver...
