Hey there,

I recently installed Kubuntu 20.04 and I had to discover that the icons on the panel/task manager are very huge, way out of proportion, as well as the whole login screen and the tools icons in Gimp.

At first the fonts were hugely scaled too but I already found out that this was an issue with nvidia-drivers and was solved by forcing the fonts dpi to 96.

Regarding the icons I couldn't find a solution neither in the system settings nor by searching online.

Those icons are only huge because you use a rather high panel, and only one line in the Task Manager widget with this.

2 solutions:
* either reduce the panel height, or
* use 2 lines in the Task Manager (right click on it to edit it)

As for the login screen: is this the default SDDM login?

I can't talk for Gimp, maybe check if you have the GTK themes adapted correctly in the System Settings

Changing the height solved it for the panel although it was already set to 2 lines. Now the colors need correct scaling as they still are as thick as with the big icons before.

The login screen is the default which came with Kubuntu, didn't change anything.

Maybe I should mention that I'm on a nvidia graphics card and using the proprietary driver version 440.

Quick update: Found an option in Gimp under Tools -> Preferences -> Icons which tells it to scale the icons according to the theme in use.

Regarding the login screen(SDDM) I'm not any further.

For the SDDM login screen, the only thing I can think of is to change the theme in System Settings -> Workspace -> Startup and Shutdown -> Login Screen
