System Tray Icon does not appear

[kayg04]

Describe the bug
I'm using the Arch Linux binary from here. I have enabled "Continue running background apps when Chromium is closed" option in chrome://settings -> advanced -> system. But there is no system tray icon visible. I'm using KDE Plasma 5 on Arch Linux.

To Reproduce
Steps to reproduce the behavior:

1. On Arch Linux with the latest KDE Plasma, download the binary from here and do pacman -Syu <pkgname>.tar.xz
2. Run chromium
3. Open chrome://settings and scroll down to advanced -> system
4. Enable "Continue running background apps when Chromium is closed".
5. System tray icon doesn't appear.

Expected behavior
Upon enabling, "Continue running background apps when Chromium is closed", a system tray icon should appear.

Screenshots

Environment (please complete the following information):

• Arch GNU / Linux w/ latest version of KDE Plasma.
• ungoogled-chromium version: 75.0.3770.142 (Official Build) Arch Linux (64-bit)

I'm not too familiar with KDE Plasma. Do they still support system tray icons? Does this happen with other DEs like XFCE?

[kayg04]

Yes, they do have system tray icons as you can see in the first screenshot. I have not tested this with other DEs. Let me try with XFCE and report back.

Hello! I just tried on an Xubuntu (18.04) system with the portable binary. No luck.

[Eloston]

I wonder if there are GN flags that determine whether system tray icons show. Any help here would be appreciated.

Just tested this and it not that the tray icon is not working, the problem is that that functionality doesn't work at all.
After enabling that option and closing chromium, there are no remaining chromium processes.

[kayg04]

I can confirm this as well.

The system tray doesn't seem to appear even on Chromium and Brave Browser (Arch Linux).

[kayg04]

So I have found a (perhaps, temporary) solution to the problem. After installing this extension, chromium successfully minimizes to system tray.

Found the extension here.

@KayGKay I suppose that's why the option is called "Continue running background apps when Chromium is closed". It's valid to not run Chromium at all when there are no background apps.

The fact that Chromium and Brave Browser have the same issue probably means it isn't our problem. Otherwise, let us know.

There's another extension called TrayEnabler which causes the same result. But in both of these cases, background apps still do not work. What I did was create an "app" out of a webpage (Wire messenger's web version) and as soon as I close the tab or the window, the process ends (as visible in Chromium Task Manager) and only a service worker remains which is not reused if I open the "app" again.

This is in contrast to Chrome on Windows where the tray icon instantaneously appears when you enable "Continue running background apps when Chromium is closed" option.
