SUMMARY
A small but annoying inconvenience: When watching Youtube videos in Firefox and using Picture in Picture mode, a new icon will be created in the task manager for the popup video. Things like floating panels or detached videos shouldn't have icons like actual dialogs and applications, which creates confusion and clutter in the taskbar.

This is a Wayland issue and doesn't occur on X11: I'm running into it since I decided to give Plasma Wayland another try with many of the core issues finally being fixed over the past months.

STEPS TO REPRODUCE
1. Open and play any Youtube video in Firefox, any video will likely trigger it.
2. Click on the icon to enable PiP mode, which should put the video into a small window.

OBSERVED RESULT

A new icon with the Firefox logo is added to the task manager for the video window.

EXPECTED RESULT

This is the sort of window that doesn't need a task manager icon. This already doesn't happen on the X11 session.

Hello,
I can't reproduce this bug. I'm on your same configuration (Reborn OS which is Arch), but the doubled Firefox icon doesn't appear (see the screenshot).

I'm on Firefox 108.0.1.

Thank you for checking. I see you have the little green + icon so I take it you use grouping, I disabled that in my configuration: If you right-click the task manager and go to "configure icon-only task manager" then in behavior set group to "do not group" can you see it then?

You are right: disabling the "grouping" feature, the PIP video creates a second Firefox icon. This doesn't happen on X11

This might be a Firefox bug, or a Wayland limitation that needs a new protocol or something.

This. No fix will be soon.
Comment 6 Nate Graham 2023-01-05 22:37:33 UTC
...Presumably this protocol: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/132. Looks like the discussion has stalled.

Added to https://community.kde.org/Plasma/Wayland_Showstoppers in the "blocked by required upstream changes" section. Will re-open once those upstream changes are merged.
