Hi @makzono
It seems Enpass is picking wrong scale factor for your display.
From the desktop, right click the Computer icon. Then go to Properties from the context menu -> Advanced system settings -> Environment Variables -> New. Please add the following environment variable to force for 100% scale on your primary display
QT_SCREEN_SCALE_FACTORS=1
Now, restart Enpass. If it looks too small, you can adjust above variable to 1.25, 1.5, 2 as per scale factor of your display.
Cheers:)
