Ubuntu 21.10
I keep getting these ghost application icons in the top bar
As you can see in the image they are only visible when hovering the mouse over them. There are so many that they have pushed my actual running app icons to the left. They appear over time and I have not been able to figure out what triggers their appearance (like a specific app I'm running). if I look at running processes I don't see 40 running apps. They are still there even if I close all applications.
Usually there are not this many but in this case you can see between the icon for Telegram and the wifi notification there are about 40 of these icons.
The only way to clear these that I have found is a reboot.
Right clicking on them does not bring up a menu.
I ran gnome-extensions and disabled Ubuntu AppIndicators. My running app icons dissapear as expected but these ghost ones do not.
I have seen other questions similar on here but they had identified the cause, that these appeared after waking up from being suspended. I do not suspend my laptop and have a tweak to not suspend if I close the lid. I checked anyway just by opening and closing the lid a few times and it does not cause these icons.
Any clues as to how I can figure out what is causing this?
Update: After a reboot they went away. So I've been watching closely to try to figure out what creates these ghost/null icons.
I just noticed one now. Didn't see it pop into existence but there it is.
Apps I have running:
- guake (has a top bar icon)
- Vivaldi web browser
- PyCharm Community Edition
- Signal (chat app)
- Telegram (chat app - has a top bar icon)
- Hotshots (screen capture app - has a top bar icon)
- gnome-extensions (the admin console)
Using the gnome-extensions app I figured out how to create more of these null icons.
If I disable Ubuntu Appindicators, when I re-enable them a null icon appears.
However, this is not what I was doing for the ones to appear out of nowhere. Something else is creating those. I'll keep digging.
