Tray icon on Gnome only works if used through XWayland

[piekay]

Expected Behavior: a tray icon appears when the option: "minimize to tray" is enabled

Real-World behavior: when enabling minimize to tray on the native Wayland version it behaves like the option isn't selected and neither minimizes to tray, nor displays the tray icon. If I enable always show icon in about:config, then the icon is displayed, but the application still behaves like the option "minimize to tray" wasn't ticked

OS: NixOS 23.05 Betterbird versions: 102.15.1 and 115.3.2 respectively Gnome-Shell version: 44.2 gnome-shell-extension-appindicator version: 53

Hmm, well, so if you enable "always on", the icon is displayed. Whether it will minimise depends on your desktop. Which desktop are you using? Gnome? Check the documentation:

System Tray support (Windows and Linux)

The following is supported:

OS / Desktop | System tray | System tray always | Tooltip with folder list | Minimize to tray -- | -- | -- | -- | -- Windows | Yes | Yes | Yes | Yes Linux / KDE | Yes | Yes | Yes | Yes Linux / Gnome | Yes | Yes | No | Yes(*) Linux / Cinnamon | Yes | Yes | Yes | No Linux / Mate | Yes | Yes | Yes | Yes(**) Linux / Xfce | Yes | Yes | Yes | Yes "Minimize to tray" on Linux from version 102.5.0 and 115.2.0. 102.5.0 only supports KDE and Gnome.

(*) For Gnome you need to install the "AppIndicator and KStatusNotifierItem Support" extension. Double-click to activate.
(**) The Mate desktop is supported from BB 115.3.1-bb14 build after 2 October 2023.

Relevant preferences:

• System tray: mail.biff.show_tray_icon (has UI)
• System tray always: mail.biff.show_tray_icon_always (no UI)
• Minimize to tray: mail.minimizeToTray (has UI)
• Linux only: mail.minimizeToTray.supportedDesktops ("kde,gnome,xfce,mate") and mail.minimizeToTray.desktopsGtkWindowPresentWithTime (special activation, "mate") (no UI)
• Start minimized: mail.startupMinimized (no UI)
• Show new count: mail.biff.use_new_count_in_badge (has UI)
• Only count unread message in inboxes: mail.notification.count.inbox_only (no UI)

102.15.1 has some of this support, but not all. So please test on 115.4.2.

Maybe issue #214 has some relevant information.

I will continue all testing on 115.4.2.

I am using Gnome with the Appindicator Extension, but on Wayland only the ```

mail.biff.show_tray_icon_always

option is working. 

I couldn't find anything helpful in the discussion you mentioned yet, but I will keep an eye on it.

Are you using the flatpak version of Betterbird? If so, there is a chance that the issue will be fixed in version 115.5.1 which will be published later today.

this seems to be an issue with NixOS. I have used it as a side project on a Laptop, but I've switched back to my main OS where this bug doesn't occur. So I sadly can't help with testing, but since this was a niche use case in the first place I guess that this won't happen again
