When I try to minimize certain snaps/flatpaks I get the red icon shown below in the system tray/Appindicator applet. Any ideas how to fix?:
The same issue doesn’t happen on opensuse budgie for whatever reason
Don’t use snaps or flatpaks unless you really REALLY have to.
Debian might not be as up-to-date as SuSE. Which release are you using? Was there not a native-packaged version of the things in your snaps/flatpaks?
