I'm not sure if this is a Cosmic issue or Pop Shell, but either way if Cosmic and/or Pop Shell are enabled, I can't copy and paste from Keepassxc at all.
Context
I believe this is related to a bug in Qtile. The only similar post I could find about it is here: https://github.com/qtile/qtile/issues/1542. The bug exists regardless of the version of Keepassxc I've tried, and exists across different package types, eg. deb, flatpak, appimage.
I found that page because I opened Keepassxc in a terminal and the error code thrown when copying is "QXcbClipboard::setMimeData: Cannot set X11 selection owner"
If all Pop-related extensions are disabled (Cosmic/Shell/Workspaces), the issue goes away.
