Client crashes on startup on Wayland/Swaywm about desktop HOT 4 CLOSED

It looks like the environment on manjaro-sway has QT_QPA_PLATFORM=wayland, which prevents Qt from falling back to xcb via XWayland. Running PIA with QT_QPA_PLATFORM="wayland;xcb" allows it to fall back to xcb/XWayland, which works in the current release.

This would affect any Qt application (statically linked or otherwise shipping its own copy of Qt) that doesn't ship the wayland backend, so IMO the distro should consider updating this value (it's suggested in a lot of resources; one example here: https://bugzilla.redhat.com/show_bug.cgi?id=1773650#c8)

That being said, it would be ideal for us to ship the Wayland platform integration too. I just had to add a few extra libs to our deployment for that to work:

It seems to work fine from some initial tests. I can't really tell from Qt's changelogs if the Wayland integration is considered complete/stable, though I would figure it likely is after all this time. We'll need to test it with a lot of DEs though; I still see anecdotal reports of problems with the Wayland integration for a lot of apps. A lot of those are older though so I'm hopeful it's complete now.

Thanks for the fast response, and sorry it took me so long to get back. Adding xcb (or replacing the existing value with xcb) does let it fall back, which is great... but now the menu when I right-click on the tray icon only has the "quit" option... and that doesn't seem to do anything. Is there maybe an app-indicator tray icon I should be using?

Here's my log in case it helps.

If the tray menu just says "quit", that means the PIA daemon isn't running. If you're using systemd, check it with sudo systemctl status piavpn. If it's not running, start it with sudo systemctl start piavpn.

The installer supports systemd, sysvinit, and openrc, and it should have detected the init system automatically. Let me know what init you're using and what the service status is, and if you're not able to start it we'll continue from there.

whoo that's great! Confirmed it was correctly installed into systemd, but disabled by default. So the only fix is to change (for my whole user) so that QT_QPA_PLATFORM=wayland;xcb.

Thanks for your help!
