This is still a problem on Ubuntu 20.04. Since it uses a completely
different desktop environment, the bug probably has a different root
cause, but the annoying user experience is exactly the same.

I too have an annoying 0.2sec delay whenever i did alt-tab switching

It's actually configurable... for some reason compiz defaults an alt-
tab delay of 0.2sec. You need to change that from 0.2sec to 0sec.
I'm on 11.04 btw.
Go to Control Center - CompizConfig Settings

Alt+Tab is very slow even with just two windows open, even if they're

right away, it can take two to three seconds for focus to change to the
other window.

Alt+Tab - switching
ALT+TAB (hold alt and keep tapping tab) with visual effects turned on is
ridiculously slow when I have a window (such as emacs) maximized. It
can take 1-2 seconds for the task-switch pane just to appear. This is
very annoying and kills productivity. Once the task switching window
appears,
Just like to add that I found this problem appears ONLY WHEN FIREFOX IS
OPEN in that workspace. My guess is that firefox is taking a very long
time to render itself into a thumbnail image for the task switcher to
display. If I close firefox or jump to a workspace that doesn't have
firefox in it,
One thing that I've found helps is to lower the fade in to something
near zero. This has more or less eliminated the problem for me.

For me, with compiz enabled, there's variably between ~0.3 and 1.5 seconds

It seems like more windows to be switched through results in a longer delay.
