xdm UI almost black after 2x scale on Linux

My screen resolution is 2560x1440. After installing XDM, the UI was too small and hard to click. Now, I can't see anything.

same here on Zorin 16, need to switch the zoom back to 100% in order to use it. Edit and set zoomLevelIndex:3 in ~/.xdman/config.txt, where 3 means 100%

I kept re-installing and looking around for a config file and came here, you're a life saver mate!
