Latency disparity between slow/fast Alt-tab tab tab hit speed

[Paul Sladen]

Binary package hint: compiz

Also discovered in breaking down bug #683635, to reproduce:

  1. Hit hit Alt-tab tab tab tab tab really really fast
  2. and then do it it again slightly slower

The first responds near instantly, and the second can lag for several seconds. It appears that there is a delay before the switch shows:

For (1) when the entire action can be completed and the Alt key released within this delay period then the window change is instantaneous.

In the case of (2) the switcher appears and then the latency (possibly a result of bug #684843) is introduced. It is perfectly /possibly/ for it to switch quasi-instantly, as can be demonstrated in the case of (1) using successive fast hits.
