When I have a Chromium window open for a while, GNOME and/or just the Ubuntu dock loses track of it. Note in the screenshot how I have a window open but there is no orange dot next to Chromium on the sidebar. I can still interact with the window with the mouse, I can still Alt+Tab to it, but I cannot navigate to it with a click on the Chromium icon on the sidebar or using Super+1 (as it is on the top of the list), both of these actions open a new window as if it isn't currently running.

As on September 24, 2020, I was using Ubuntu 19.10 and GNOME Shell 3.34.1. But then later on, I upgraded to Ubuntu 20.04 and I'm still experiencing this issue.

  • Does this issue happen with any other app? – technastic_tc Oct 7 at 9:18
  • I've only noticed it with chromium, and it doesn't happen immediately. I have a hunch it might be related to when memory gets low and/or laptop sleep/suspend, but I haven't figured out a consistent repro. – jaltekruse Oct 7 at 13:48
  • Which version of Chromium are you using? Is it the latest version? What are the steps you followed to install Chromium? – technastic_tc Oct 7 at 14:22
  • BTW, what is the GNOME version which you have right now? – technastic_tc Oct 7 at 14:29
  • Version 85.0.4183.121 (Official Build) snap (64-bit) GNOME Shell 3.36.4 I believe that I installed it though the Ubuntu Software Center, here is how it reports there (although I know you can also install outside debs though the center too, so it's possible I did that). Channel: latest/stable, Version: 85.0.4183.121, Developer: Canonical, Source: snapcraft.io – jaltekruse Oct 7 at 15:09


It looks like this has been reported to the dash-to-dock project and is still open.

Thought it would be worthwhile to at least post the quick workaround mentioned in that github issue here until the devs can address the issue.

"Only way I've found to solve it when it happens is to do an "alt+f2" and type the "r" and enter to reload the entire gnome-shell."
