[BUG]: App immediately freezes on Gnome 46 with Wayland

[kimdre]

Brief description of the issue

I'm using the flatpack version of 4.6.6 on Fedora with Gnome and Wayland.
As soon as I start the App, it immediately freezes and does not respond to any inputs and can only be hard killed.
When I start the app in an X11 session, it starts normally.

How to reproduce the bug?

1. Start app (either with desktop icon or flatpack run command) in an Wayland session in Gnome
2. App starts and freezes

What was the expected result?

App starts normal and can only be hard killed

What actually happened?

App starts but does not respond. After a while a window appears to kill the app.

Operating system and version

• OS: Fedora Linux 40 (Workstation Edition)
• Gnome 46 with Wayland
• RSS Guard version: 4.6.6

Sigh...

I might have to force XWayland for the Flatpak package until we figure this out.

[guihkx]

I could not reproduce this on a virtual machine with GNOME 46 + Wayland:

@kimdre Can you try to reproduce the problem with 4.7.0?

If the problem persists, try a fresh run? I.e. by renaming or removing ~/.var/app/io.github.martinrotter.rssguard.

If that doesn't work as well, can you share your config.ini here? It's in ~/.var/app/io.github.martinrotter.rssguard/config/RSS Guard 4/config/.

[kimdre]

Renaming the ~/.var/app/io.github.martinrotter.rssguard did not work unfortunately. RSS Guard just opened with the default settings and design and froze again.
Here are my config.ini contents: https://gist.github.com/kimdre/a2122fa3780e9874dcddae1b0c7fcca3

[martinrotter]

Does the same problem happen for Lite version?

[kimdre]

Yes the Lite Version does indeed work.

[guihkx]

Thanks for the config file, but unfortunately I still couldn't reproduce the freezing.

The Lite version not freezing could be a clue, but at the moment it doesn't ring any bells for me...

I can't think of anything obvious to debug this further, except using gdb to perhaps understand where the app freezes...

[kimdre]

I will check it again when Nvidia releases its new v555 driver. Afaik it will solve a couple of issues on Wayland, so maybe this could be also related.
