ToneLib-Zoom High DPI Scaling on Linux

I'm running Debian Gnome on a laptop with a HiDPI screen and ToneLib-Zoom doesn't scale properly with the GUI being too small to comfortably use. I'd appreciate it if someone could help me with this as I can't find a solution and it's the only app for my pedal that I can actually get running on Debian.

Thanks in advance and let me know if any more information is needed.
