I am currently having the strange problem that the app window does not refresh itself when interacting with it. I have to put it out of focus and back in focus to repaint.
Example workflow:
Typing something in the search field (or any other action like scrolling, unlocking, editing or whatever).
(Action is not reflected on screen, like if it was hanging)
cmd+tab to a window that would be completely in front of the Enpass window (covering it as a whole).
cmd+tab back to Enpass -> et voila, I see the result of 1.
Software: Enpass 6.3.3 (584), macOS Catalina 10.15.2
Hardware: MacBook Pro 16" with AMD Radeon 5300M 4 GB and Intel UHD Graphics 630 1536 MB (maybe a rendering problem with new MacBooks on Catalina? Worth troubleshooting if you have such a device :) )
Thanks
Arne
