Increase font size in Recorder?

My video display is 4K and the text in the Recorder app is small.

Are there any options for scaling or font sizes?

Are you using Java 8 or 11?
It looks like 4k support was only introduce in Java 9.

Java 11

Sorry, not much we can do (hands full, no such display).
A contribution for 4k support would be much appreciated!
