Locally-installed apps' icons not showing

[jaymot123]

I'm running two software defined radio-related apps, SDR++ and VirtualRadarServer's Linux Mono version and they both show a generic gear icon in Docklike. Their Whisker Menu launchers show the correct icons. They aren't pinned in Docklike, they just appear there when I launch them from Whisker. I used A La Carte to add VirtualRadarServer to the Whisker menu as I launch it from a shell script which also opens dump1090-fa in a terminal. SDR++ was installed from a .deb package downloaded from its developer's github page.

SDR++ launcher:

OS: MX Linux 21 beta 1 based on Debian Bullseye, Xfce 4.16, Docklike version 0.3.0 packaged for MX on 2021/07/26. I installed the Window Buttons panel plugin and the icons are displayed correctly.

More information: these apps' icons don't have right-click context menus so I can't pin them to the dock. Also I just installed Viber's desktop application for Debian-based Linux and get the same behavior.

Hey guys install menu editor and use that to edit the desktop shortut of the app that is playing up, while editing the shortcut go to advanced and click on Startup WM Class. It will than want you to click on the windows you want it to use and that will fix it.

Hey can you be more specific about what do you mean by menu editor?

I have switched to electron wrapped apps instead of chrome shortcuts because the doc doesn't distinguish chrome shortcuts, but now I can't pin my electron apps to the dock.

Hey just install menulibre and create or edit the current desktop shortcut, go to advanced and click on Startup WM Class and that will allow you to click on the electron app and set it to the desktop shortcut
