Description Tony 2017-05-04 17:48:33 UTC

I noticed this behavior with Firefox on wayland.

Firefox icon, with the default task manager on the panel (not the icon one), "moves" between other icons when switching tabs with different web pages.

To reproduce:

Open "Dolphin" 
Open Fireofox and some pages, different ones.
Start switching between tabs.

You'll notice Firefox icon will move from either the right or left side of the "Dolphin" icon as you switch tabs.

BTW forgot to mention this happens even with "Lock widgets" on.

Could you add a screenshot of your Task Manager's config dialog so I can reproduce your settings?

This is basically because on Wayland we currently don't have all the window metadata the Task Manager needs for sorting, so the window title ends up being the sort string (to simplify), so the moving happens because the window title changes as you switch tabs.

Well wayland's got it's metadata for sorting, its fixed, can't reproduce anymore, all good on Neon and opensuse.

Making it "works for me" since i don't trully know if it is properly fixed.

Likely got fixed when we improved the app identification heuristics on Wayland by sharing them with X11.
