[SOLVED] Display density problem on Ubuntu

Having trouble with LMMS? Ask about it here.
Hi there,

I just installed the latest .AppImage of LMMS (lmms-1.2.1-linux-x86_64.AppImage) on Pop!_OS 19.10 (highly derived from Ubuntu) and the display density is too high :

I am running lmms on a laptop at a resolution of 1920x1080.

What is the issue here?

Thanks
