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. submitted by /u/zquestz [link] [comments]
