Right-click context menu does not appear

[iainelder]

Summary

On my Ubuntu 24 desktop with the default window manager, right-clicking items in the folder list and the video list produces no context menu. Only the mouse-hover tooltip appears. Launching Tartube via XWayland (GDK_BACKEND=x11) works around the problem.

Environment

• Tartube: v2.5.197
• Installed via: python3-tartube_2.5.197-STRICT.deb from the GitHub release
• OS: Ubuntu 24.04.4 LTS
• Desktop: GNOME Shell 46.0 on Wayland
• Python: 3.12.3
• GTK: 3.24.41

Steps to reproduce

1. Launch Tartube with the default window manager via the terminal (tartube, no env overrides)
2. Click the toolbar Folder button, name the folder, OK.
3. Left-click the new folder in the video index to select it.
4. Right-click it.

Expected

Context menu appears with Check folder, Download folder, Delete folder, etc.

Actual

No context menu. After ~1s the row's normal hover tooltip appears, but no popup is shown. No visible error in the UI.

Console output on right-click:

Gdk-Message: Window 0x39e74eb0 is a temporary window without parent, application will not be able to position it on screen.
(tartube:10560): Gdk-CRITICAL **: gdk_wayland_window_handle_configure_popup: assertion 'impl->transient_for' failed

Shift+F10 and the keyboard Menu key also do not open the context menu.

Workaround

Launching via XWayland resolves it completely:

GDK_BACKEND=x11 tartube

All right-click menus then work as documented.

Scope

Confirmed on right-click of folder rows in the video index and of downloaded video rows in the right-hand pane. Channels/playlists not tested; none added yet.

Workaround for the app menu launcher

To make the workaround apply when launching from the Gnome app menu, I used these commands.

cp /usr/share/applications/tartube.desktop ~/.local/share/applications/
sed -i 's|^Exec=|Exec=env GDK_BACKEND=x11 |' ~/.local/share/applications/tartube.desktop
update-desktop-database ~/.local/share/applications/ 2>/dev/null

After this, the Exec= line reads:

$ grep -E '^Exec=' ~/.local/share/applications/tartube.desktop
Exec=env GDK_BACKEND=x11 tartube

Then I can launch Tartube from the app menu and use right-click menus.

The user-local .desktop file takes precedence over the one installed by the package and should survive any package updates.

I tested this on a clean Debian system, installing python3-tartube_2.5.197-STRICT.deb, but could not reproduce the missing context menu.

Apologies, Ubuntu 24.04.4 LTS is unable to install itself on my system, so I can't test it.
