Recently installed Parrot OS on a Dell XPS 9370 Which has a 3840x2160 display, and there seems to be a small scaling issue with the "Notification Applet" on the top right hand corner of the screen. They seem really close together and are bunched. When turning off the high DPI settings it reverts to normal.
I've attached an image so you are able to see. I've had a look around and havn't found anything online about this so I thought I'd raise an issue here
