I'm running Gnome 3.28.2 with wayland. I upgraded Qt5 from 5.10.1 to 5.11.0, which causes a broken theme and all kinds of other UI glitches. Also copy / paste is broken, due to the wayland sandboxing.
I think this is caused because Qt 5.11 changed the default platform plugin from xcb to wayland.

If i run keepassxc -platform xcb everything works fine.

I'm sorry if this is a duplicate or an upstream bug, but i did not see this reported anywhere else and since other qt apps (like vlc) handle this fine, my first guess is that the bug somehow relates how KeepassXC handles wayland.

Expected Behavior

Current Behavior

Workaround

Run keepassxc with the keepassxc -platform xcb flag or downgrade qt to v5.10.1

Maybe a temporary solution would be to change the .desktop file to run keepassxc with the -platform xcb flag by default for now.

Steps to Reproduce (for bugs)

1. Install Qt version 5.11
2. Start keepassxc

- OR -

1. Install Qt version 5.10
2. Run keepassxc -platform wayland
