I just started getting this popup from Dropbox on Wayland + Sway (with lots of gtk apps). Prior to this, the Dropbox app indicator icon was working fine in waybar.
The linked Dropbox doc page from the popup’s Learn more button talks about checking XDG_CURRENT_DESKTOP for a very limited set of “supported” desktops (e.g. Unity, KDE Plasma, GNOME, XFCE, MATE). For my Wayland + Sway machine it’s set to: XDG_CURRENT_DESKTOP=sway
Currently I have installed:
aur/dropbox235.4.5905-1extra/libayatana-appindicator0.5.94-1extra/libappindicator12.10.1-1
Is there anything else that is now required? Maybe Dropbox app developers are unaware that their app worked fine previously on Wayland + Sway without many extra packages?
