Comment 3 Nate Graham 2023-04-04 18:47:28 UTC 
This happens because the Task Manager fails to map the open Emacs window to the desktop file used for its launcher. Perhaps it changes its desktop file or its NET_WM_STRING property after being launched, which can cause this to break. Ultimately this is a bug in Emacs itself; I'd recommend reporting it to that app's developer. Thanks!
