You're right, it shouldn't be running automatically or at the very least it shouldn't be showing up in the alt tab interface. I would suggest launching the extensions that comes with gnome and turning off any extensions that aren't default. The hope is that one of those is causing the process to spawn. You may also want to check what applications are set to autostart. There may be something there that is causing the issue.

If none of these work I suggest setting up an account over at https://chat.pop-os.org there may be someone in the community that has dealt with this problem.

gjs is the JavaScript runtime that GNOME uses for GNOME Shell. All JavaScript scripts operated under GNOME Shell are being interpreted by /usr/bin/gjs. You need to find out what script is being executed that's creating a window.

We have a few users in Mattermost reporting gjs in the alt-tab menu and/or a blank icon showing up in Activities on 20.04 when Show Minimize to Tray Windows is enabled (the default setting.) I am not seeing this on my 20.04 test machine, but I'm re-opening the issue for further investigation.

On my system (Pop! _OS 20.04 LTS) the ghost icon appeared with Show Minimize to Tray Windows enabled and the GNOME WindowOverlay Icons extension enabled as well. I disabled WindowOverlay Icons and the ghost icon disappeared. If I leave WindowOverlay Icons enabled I have to leave Show Minimize to Tray Windows disabled so the ghost icon doesn't show up. Of the two options, I preferred to disable WindowOverlay Icons.

Below is the image of my system with the ghost icon appearing. As I disabled the WindowOverlay Icons extension (https://extensions.gnome.org/extension/302/windowoverlay-icons/) the issue was resolved. The Show Minimize to Tray Windows option is enabled on my system.

It seems there are two separate issues here.

1. DING + Wayland -> stray icon in Alt-Tab switcher.
2. WindowOverlay Icons extension (third-party) -> stray icon in Activities. (I can recreate this on X11.)

I would assume at least the second one can be fixed by adding something to the list of skip taskbar exceptions.

@henriqueffc - can you check if this happens with WindowOverlay Icons ext also turned on in the latest master branch?

Yes. The icon still appears if WindowOverlay Icons and the Show Minimize to Tray Windows option in the Pop Shell are enabled together. If Show Minimize to Tray Windows in Pop Shell is disabled, the icon no longer appears. I use Pop!_OS 20.04 LTS and the system is up-to-date.

The wm_class for the root in 3.36 is Gnome-shell where 3.38+ is now Gjs

@henriqueffc or @jacobgkau - how do I repro the Alt+Tab with DING Gjs? Not sure if the new PR will fix it?

I'm able to recreate that one by enabling Wayland (comment out WaylandEnable=false in /etc/gdm3/custom.conf) and logging into a Wayland session using the gear in the bottom right of GDM. (The gear doesn't show up on an NVIDIA system, I'm using an Intel system to test.)

#1131 doesn't seem to fix that one (but it does fix the WindowOverlay Icons extension on X11 case.)
