20.04: icons in task switcher belong to parent program

Ask Ubuntu Asked by Joe Corneli on October 25, 2020

In these pictures we see how the subprocesses of Emacs inherit the "Emacs" icon. That’s a bit confusing when the subprocesses are actually, e.g., Mozilla Firefox (pictured here) or Evince.

This seems to be new behaviour since I upgraded to the latest LTS.

Before, subtasks would have their own icons (e.g., Firefox in this case). Can that behaviour be restored?
