Previously, I did not find any fix for WB HUD problem on Ultra HD resolution (3840px x 2160px). For this reason, I started to try to find a solution, which I found after some attempts. It is very simple. Just change high DPI settings in World Builder Windows application compatibility options. Override high DPI scaling behavior. Choose scaling performed by the system.
Enjoy and create great maps.
Before:
High DPI options: Sorry for Polish language.
After:
System: Windows 10 Pro x64.
WorldBuilder version: 4.0.0.23369.
