Launcher appears when switching between workspaces with fullscreen windows

Bug Description

Binary package hint: unity

I have the Launcher set to 'Dodge Windows'. Whenever I switch workspaces from one with a full screen window to another, the Launcher briefly appears and then 'dodges' away. This behaviour is quite annoying, could it be changed to stay hidden in such cases?

I can't reproduce that behavior unfortunately, can you try to give some concrete steps to this? (I have two maximized window, one of each worskpace), and typing ctrl + alt + right to switch to the other ws: no launcher appearance.

Also, a video with gtk-recordmydesktop can help.


Changed in unity (Ubuntu):
status: New → Incomplete

Ah, looks like I am able to get the behaviour only when I set the key bindings to Super+Left, Right etc. In fact, the behaviour doesn't seem to be limited to switching workspaces, the Launcher intercepts any Super+Key shortcut and shows up temporarily. This is probably because its (default) keybinding is set to Super. If that's the case, two questions:

1. Isn't a key binding of Super supposed to imply Super key Down + Up, as opposed to Super key Down + Some other key?

2. I tried setting the key binding to something else, like Super+L, this fixes the issue. However, now Super+L only shows the Launcher with the icons, but not the entry box with the shortcuts / search results displayed etc. I am not able to invoke that at all using a keybinding unless its set to Super (the default), I have to click on the Ubuntu icon at the top left every time.

I have attached a desktop recording showing the issue.

Probably this is the same as #704231 ?

right andy, you got it. It's a general keybinding issue, not a wrong launcher behavior :) dupping it! Thanks :)
