Demystifying StartupWMClass

StartupWMClass is NOT needed if the .desktop file is named correctly.

Yeah in your case the best fix is probably REMOVING StartupWMClass from those launchers if it is present. Then it will only match the app id on the .desktop file name.

Yep it has both applied. What are the actual .desktop file names?

Yeah something isn’t being matched right. Might want to look at both .desktop files and compare them. Probably be pretty obvious when you look. =)

I actually use that logo for my app menu.

You can think whatever you want.

As the maintainer of Plank Reloaded, the most common bug report I get is “this app has the wrong icon.” It’s almost never the dock - it’s a broken StartupWMClass in the app’s .desktop file. So I wrote up how to find the right value on X11, Wayland, and KDE, and why deleting the line often fixes it.
