[Bug 836023] [NEW] New compiz alt-tab switcher window is slow to appear


Public bug reported:

I am using the new alt-tab switcher in Oneiric. When I press alt-tab the
window switcher takes just a little too long to appear. Releasing alt-
tab during this period will generally work (I've seen it miss presses
but this no longer happens after the latest upgrades) but the switcher
won't appear until half a second later.

I don't know if the window is slow to render or this is just a timeout,
but it feels slow and somewhat annoying when you have many windows (and
you need to see the window before you can select the correct one). I'd
appreciate it if this could be made faster or even configurable.
