Does LibreOffice have a maximum window resolution on Mac?

I can’t use my full (external) screen with LO Draw! Resizing the window to max produces the result in the screenshot. Is there a way to change this? How?
LO Version:
Mac OS 10.14.4
MBP 15" retina mid 2015
1080p Samsung screen

Resizing to 720p works, but then everything is blurry… Not so good.
