In Task switcher I see generic X icon for Ferdium. Everywhere else (docks, menu, taskbar) I see the correct icon.

Hi @jasmines, how did you install Ferdium on your ubuntu? Relatively to that: do you know if you already have a .desktop file for Ferdium installed? This is where the settings for the task manager/dock/etc. to use would be stored (in particular the icon: field). If you used the AppImage, you might want to create a .desktop file by hand yourself (we haven't created a way to do that automatically yet).

[jasmines]

Installed as snap, .desktop file is created upon installation: /var/lib/snapd/desktop/applications/ferdium_ferdium.desktop

The icon field value you read is right, and it actually works in taskbar and docks BUT NOT IN TASK SWITCHER.

Ok, thanks for the precision. It looks like KDE is using a different way to deal with icons for the task switcher (see this answer) and you might be able to ask it to use the icon from the desktop file. I will check if there is a way to make the app report the same icon in general during run time. If you know of another electron app that behaves appropriately, then I would be glad to know in order to see if we could replicate what they did.

[jasmines]

Are you suggesting something to solve? I can't find the hint in the answer you're referring to.

I ran into the same issue and worked around it by creating a custom .desktop file under ~/.local/share/applications and setting the Icon value to the icon that ships in the snap, and forced Plasma to always use that .desktop file.
