Description Luis Mayo 2024-10-29 19:08:00 UTC

SUMMARY
When launching via CLI certain flatpak apps based on GTK (Bottles and Video Trimmer, at least) I receive the following error:
`Gdk-Message: 19:45:49.119: Error 71 (Protocol error) dispatching to Wayland display.`

If launched through start menu it just fails silently

STEPS TO REPRODUCE
1. Install Bottles flatpak through any means (for instance: Discover)
2. Try to launch it using `flatpak run com.usebottles.bottles`

OBSERVED RESULT
It fails with:
`Gdk-Message: 19:45:49.119: Error 71 (Protocol error) dispatching to Wayland display.`

EXPECTED RESULT
It launches

Sounds like a bug in the app itself.

It may be!
However this doesn't happened a few updates back and it's happening on two different apps. Maybe it's on the GTK Flatpak runtime?

Can't reproduce here. Could you attach the full log here? Ideally with the app launched with WAYLAND_DEBUG=1 set?

I've attached the requested log to the issue. The command was `WAYLAND_DEBUG=1 flatpak run com.usebottles.bottles &> bottles-wayland-bug.txt`

Thanks a lot for your time!

This is a bug in the NVidia driver, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11723 (I haven't found an NVidia issue about this, but they're aware of this)
