Same problem. Funny thing, the first few days with Enpass 6 there were no problems. Everything is not in the right place now. For example if I click Dropbox in my picture then Google Drive shows up..
I tried to repair, to reset, and to reinstall, but nothing helped. I found out that when I go to System-settings -> system -> Display -> "Change the size of text..." to 100% and restart Enpass then it's fine - but then I need a magnifier for everything Normaly my setting is 225% (250% recommended from the system).
I use a Dell XPS Laptop with the 4K Display.
