Comment 117 for bug 767095

Rather than recompile compiz, why not just use Habib's suggestion in comment #42 to work around the problem? ie create a script called, say, '/usr/bin/skype-delayed' containing something like:

#!/bin/bash
sleep 15; skype

and then change your startup applications to run skype-delayed instead of skype.

I've found that a 15 second delay works better than 10 seconds, possibly because Unity takes so long to initialize.
