Started crashing on startup after system update

Describe the bug streamdeck-ui crashes on startup. I don’t think this is due to a change in streamdeck-ui itself, but possibly pynput, Gnome, or Wayland. But I figured I’d start here and work my way down the chain. It used to work, but stopped in the last few days.

I checked my pacman log, the only relevant python/gnome/wayland/streamdeck packages updated within the past few days were gnome-shell (1:43.1-1 -> 1:43.1-2) and python-elgato-streamdeck (0.9.1-1 to 0.9.3-1).

To Reproduce Steps to reproduce the behavior:

1. Run streamdeck from terminal
2. Review console output
3. See error

Expected behavior Application runs

Screenshots Error log:

Hi there, circling back on this as we haven’t had any recognition from the dev staff yet for this xorg bug.

A workaround for those landing here from Google:

1. Run: $ xhost +
2. Run: $ streamdeck

This will allow the app to launch however I think this is somewhat of a workaround and not a proper fix. Any assistance from the dev team would be appreciated. Thanks!

Hi, I’m the package maintainer of streamdeck-ui on Arch and I can confirm that a 100% fresh build with Gnome 43 produces this bug. I’m happy to provide testing resources as well as providing any detailed troubleshooting that might be required.
