Launcher: visual feedback when moving mouse over launcher item is delayed

[Greg A]

For example: if I move my mouse over the Firefox logo in my launcher there is a small delay (over half a second I reckon) before "Firefox Web Browser" pops up. This delay is confusing (I assume it's unintentional) and a regression from 11.04

I'm fairly sure this is not a regression in the strict sense. Anyway, adding the design team for feedback, I think this was an intentional change. You'll notice as well that after the first appearance of the tooltip if you move it along the launcher it appears almost instantly.

[Sebastien Bacher (seb128)]

duplicate bug #804021? the rational for the change was bug #687956

[Brendan Donegan (brendan-donegan)]

Yes, it's a duplicate. FWIW I don't agree with the sentiment of this bug - the submitter of bug #687956 makes a good point - why do you need to the tool tip? After even a short time using the system you'll be familar with what the icons are. It just gets in the way. A short delay before displayed is time-honored tooltip behaviour, otherwise we'd have them popping up all over the place.
