Problem with the widget "Plasma Drawer" (wrong scaling for 2560:1600 resolution)

Background does not cover all of the screen. It looks annoying. Here is the photo of the problem (look at the lower and at the upper side):

Sorry for the photo from the mobile, idk how to make a screen while I’m here.

I couldn’t find the way how to change this.

And I really don’t want to change plasma drawer, cause overall it looks nice.

p.s. Problem is only with the confirmation of restart, shut down and etc…

bruh only kubuntu problem

works on fedora
