Code review comment for lp:~smspillaz/compiz-core/compiz-core.work_923683

Try using valgrind/callgrind to simulate a slow machine. You will see a monumental difference in performance when dragging windows. Even my i7 (running callgrind) can't keep up with dragging windows using this branch. But it is almost perfectly fluid without this branch.

Maybe it is the fact that all motion events are getting though now. But regardless, people with slow-to-regular machines will be noticeably impacted. We need a fix before accepting this.
