17.10 gnome icons don't reflect/use existing open windows in certain applications

[Paul Tichy]

In Ubuntu 17.10 using ubuntu or gnome desktop, certain application icons do not work properly. Specifically unpinned apps don't appear in Docky (gedit), once launched, open app indicator icons do not appear (gedit, libreoffice writer, calc, GIMP). If one of these applications is opened, clicking on the icon in docky launches a new instance rather than switching to an existing instance. Changing back to unity desktop resolves the issue.

I attempted several workarounds, including deleting and readding icons to dock, uninstalling and reinstalling Docky. No luck with any. Verified on four other computers from different manufacturers. Consistent problem that appears to be application-specific. For example, Firefox appears to work properly.

More information on this bug. It appears to be a Wayland problem. Things appear to work properly in Gnome with an Xorg session.

I was able to reproduce this bug by removing the ubuntu dock from GNOME Shell 3.26.1 in distribution 17.10.

Please look at the method that docky for grabbing context from a gtk window

   sudo apt-get remove gnome-shell-extension-ubuntu-dock
   sudo apt-get install docky
