High DPI support on Linux

[karasu-jp-com]

This is what you get with ubuntu set to 192dpi!
Either something is wrong, or NappGUI doesn't support high DPI in the first place.
I need to determine if it's possible to develop using this.
Any advice would be appreciated.

Additional notes:
Here's what I'm using around the environment
