STEPS TO REPRODUCE
1. Open System Monitor

OBSERVED RESULT
The wrong application name is used.

EXPECTED RESULT
The correct application name is used.

SOFTWARE/OS VERSIONS
Linux: KDE Neon
KDE Plasma Version: 5.21.0
KDE Frameworks Version: 5.79.0
Qt Version: 5.15.2

Can you provide the output of systemd-cgls when this happens? We map from cgroup name to desktop file, I'm quite surprised it ends up at telegram.

Here is the requested output.
Comment 4 Arjen Hiemstra 2021-02-22 11:43:55 UTC 
So, firefox is placed in a cgroup named `app-appimagekit_d98825e589ea79557384fe149efdfbdd\x2dTelegram_Desktop-f9d4173cdb23432da46641d8d924ad4a.scope` which means we end up mapping that to Telegram.

What I suspect happens, and please correct me if I'm wrong: You start Telegram, then from Telegram open a link that starts Firefox. After that, you close Telegram again.

Telegram apparently just starts Firefox blindly instead of going through something like xdg-open which means that Firefox ends up in Telegram's cgroup. So it looks like this is something that needs to be fixed in Telegram as there is no way to influence its launch behaviour currently.

I tried closing and opening Firefox again and it seems your intuition is true: Firefox is now shown with its own, correct name. I will open a bug report in Telegram's repo. I am marking this bug as "resolved upstream".
