This is a regression from quantal -- can someone confirm this is intended behavior or not? Under quantal you do not see an alt-tab bar appear when switching quickly.

I think it is unclear what the desired result is here. On 15.10 when I press quickly you can see the alt-tab switcher appear for a few milli-seconds before the desired window appears, but just barely. Does this count as a pass or a failure?

Well, basically right now there are about 80ms to show the window, so it really depends in how fast you are.

In generally showing the view quickly is good (as if you want it to be presented is not nice to have a longer timeout), while it's not possible to predict what kind of switching the user will be, and thus showing it for a few ms before closing it again, IMHO is better than waiting longer to see it when you want that.

Maybe we might make those timeouts tunable from settings, though.
