Support IntelliJ "New UI"

[aronschmidt]

Is your feature request related to a problem? Please describe.
Using the New UI in IntelliJ with Hiberbee leads to some problems.

1. Inlay Hints shows an author icon, but it's much too big
   

2. Commit Tool
   

3. Settings Icon invisible
   

4. Git Tool icon sometimes gets really big, blowing up the whole left toolbar

I think most of these issues are related to display scaling on my MacBook and occur after switching displays from "internal only" to " internal + external".

Describe the solution you'd like
Correct scaling/placement/visibility of icons, no matter if I change my dispaly layout/settings.
