Minimized App icons not showing in Panel

I have taken an odd liberty of Combining Several threads all noting the same issue into one in order to try to help narrow down the troubleshooting.

If, ultimately, one users issue is resolved but others are not - we can separate them out. But as the issues are so similar, I suspect a similar root cause.

The ZorinGroup has responded to this issue with this message from Zorink (Kyrill Zorin):

In order to narrow down whether it's an issue with the AppIndicators shell extension or Discord, perhaps it might be helpful to try installing an alternative system tray extension – like "Tray Icons Reloaded" – to see if the error still occurs. It can be installed on a stock Zorin OS 16 system by following these steps:

  1. Open the Terminal and enter this command: sudo apt install gnome-tweaks chrome-gnome-shell
  2. Open the Zorin menu > search & open "Extensions"
  3. Switch off the "Zorin AppIndicators" extension in the list and close this window.
  4. Navigate to this page in the Firefox web browser: Tray Icons: Reloaded - GNOME Shell Extensions
  5. Select the option to install the Gnome browser extension and follow the on-screen instructions to complete the process.
  6. After the browser extension is installed, reload the webpage for the "Tray Icons: Reloaded" desktop shell extension.
  7. Click on the switch to turn on this extension, and accept the prompt to "Install" it.
