That bug is not fixed. I can confirm this for 14.04 trusty. – If MC
Return is right, this bug isn’t fixed either.

I'm here from bug 1007857. I have tried to make a video of the problem,
but the stuttering doesn't look that bad in the video. I think my phone

I am from bug 1100456 and I have to say that it does not look like

compiz-core that is not yet pushed to the archives) so I got a compiz-

To clarify - the feedback loop is a worse-case that is still better than
the best case that we have now. It doesn't cause constant redraws,
rather, it just means that the nux windows will always be drawn to the
screen every time a compiz window updates. The cost is not that bad - as

Hmm, would you accept a fix to this if it worked in the normal case, but
