Just installed AudioTube

I run Fedora Silverblue 38 w/ Wayland + Mutter.

[Justinzobel]

Interesting as I'm on Fedora KDE with Wayland and it doesn't happen on my NVIDIA GPU desktop or my Intel GPU laptop.

I posted over in the forum as well to ask the other user, it may be something to do with the GNOME desktop.

[Justinzobel]

@jbbgameich can hopefully check out the backtrace as well.

[hfiguiere]

it goes deep. This is the short version.

[Justinzobel]

Jonah will ask for the full trace if needed.

[njic]

Can I provide more logs? And how?

[jbruechert]

Can you try whether deleting ~/.var/app/org.kde.audiotube/cache/KDE/audiotube/qmlcache/ fixes it?
There is some long standing issue with qml caches. Since ostree does not preserve the modified time of the files, Qt doesn't know when they were changed to regenerate the caches.

If that doesn't help, does flatpak run --env=QT_QUICK_CONTROLS_STYLE=org.kde.desktop --env=QT_STYLE_OVERRIDE=Breeze org.kde.audiotube work?

[hfiguiere]

In my case it was a fresh install, but I tried this just in case and get the same result.

[hfiguiere]

It seems that this cause a recursive call that smashes the stack. I am at statck frame 3134 and still not finished.

The pattern:

THX

Deleting cache didnt help, but that run command is working! What can I do now to start it without terminal?

[hfiguiere]

Sorry I hadn't seen the edit:

That does work, indeed.

The output in the console differ

With this command line I have:

Without (before it crashes):

I wonder if that difference is not related to the problem
