First of all the new gui is nice and does not suck
That out of the way, I was also affected by this.I am using Ubuntu 18.04.1 LTS (community theme "yaru") on a 1080p laptop (X11, not wayland).
As a workaround I followed the suggestions in the FAQ and created the following file:
after this I made the file executable
chmod +x /opt/enpass/enpass_launcher
and changed the desktop launcher in
to look like this
GenericName=Enpass Password Manager
make sure to completely close Enpass (including the tray applet). After re-opening, the scaling should be back to normal.
It would be great if future versions of Enpass improved the resolution detection to avoid fiddling with system files which is not for everyone. If you need any additional info about my setup to help you improve your software let me know!
