This is a very pedantic question. I'm using Ubuntu 16.04.3 LTS on my desktop and recently switched from Unity to Ubuntu Gnome (3.18.5). I'm using the excellent Dash to Dock extension.

My pet peeve is that when I open an app that I installed, it is not highlighted with a blue line in the dock, unlike system apps like Terminal. For example, the Brave browser that is open here -

Brave no highlighted

Moreover, if I click on the icon for Brave again, it closes the running instance and starts a new one. If I enable "Show Running Applications" from the extension settings...

... the running application is shown as a new instance in the dock, unnecessarily extending it.

How can I get my system to highlight the running app at its place in the dock itself?

EDIT : This lack of highlight only happens for apps that I've installed later - using snaps or PPAs.

  • Does this happen with Brave only? What about Firefox? What about another app you installed? – pomsky Aug 4 '17 at 4:32
  • It happens with any other app I installed. For e.g. Keepass (icon next to Brave). – fwx Aug 4 '17 at 5:07
  • Strange! Do you have Launch new instance (extensions.gnome.org/extension/600/launch-new-instance) or something similar activated? – pomsky Aug 4 '17 at 6:25
  • Nope. Checked that already. – fwx Aug 4 '17 at 6:36
  • What happens when you're in the 2-icons-situation as in the 3rd screenshot, if you right-click and Remove from Favourites the icon without the running indicator and Add to Favourites the one with indicator? – pomsky Aug 4 '17 at 6:44

In the Dash to Dock settings, try these settings...

Update #1:

The user's problem only occurs with snap applications. Suggested to contact the author of Dash to Dock and report a bug.

  • Thanks for the reply. Unfortunately, this does not work. It only replaces the blue highlights with dots. And that too, only for the pre-installed apps. – fwx Aug 4 '17 at 18:23
  • @user1649740 I just checked mine, and it properly shows the white dot for running apps that weren't installed as favorites. You might write the author of DtD and see if they can help. – heynnema Aug 4 '17 at 18:55
  • ps: I wonder if it's a bug... move the dock back to the left side and see if the white dots show up. – heynnema Aug 4 '17 at 18:57
  • @user1649740 Are the only icon/highlight problems that you're having are with snap applications? If so, I'd report that to the DtD author. – heynnema Aug 4 '17 at 23:24
  • 1. Moving the dock to the left did not affect any change. 2. Yes, currently, the problem is only with applications installed as snaps. Moreover, every time I click on the new icons, a new instance of the app is generated rather than pulling up an existing one that is already running. – fwx Aug 5 '17 at 4:12
