Applications like EndeavorOS Welcome, Tor browser won’t show their actual icons on the taskbar after Gnome 46 update. I have observed that applications launched by invoking the binary through terminal using ./ behaves this way. (Not sure about the EOS Welcome) Is there any fix to this?
OS: EndeavourOS Linux x86_64. DE: GNOME 46.1. Icons: Papirus [GTK2/3].
[Edit: This is not a freshly installed system. Icons were working fine till Gnome 45.]
Check what is in the desktop file first. If the icon name is misspelled there, it won’t work with any icon pack ever.
I know how this works because the same happened to me with Thunderbird, at some release they changed the icon name in the desktop file, but it wasn’t updated in my icon packs, I expect something similar here as well. Without checking this you can’t be sure who’s fault is this, but I guess the app’s developers or maintainers messed up their desktop file some way.
