Hi1
I noticed an issue on ubuntu-mate with some snap packages not showing the icon in the appindicator.
It is fixed if I append "Unity" to the env variable XDG_CURRENT_DESKTOP.
But then the programs that have ShowOnlyIn=MATE (like caja) do not show in the menu.
Is there a different way to fix this?
One example of snap package is Whatsie, but also other ones (I'll test it with the env variable reset to the original value).
The versions of ubuntu-mate on which this happens are 20.10 and 21.04, I haven't tested older ones.
I don't use Snaps, but can't you just make your own icon? I do it for other programs that don't have icons in the theme set. This is from a previous post:
The problem is not that the icon is missing, but that the appindicator does not show it (unless I append Unity to the env variable XDG_CURRENT_DESKTOP)
