Screencasting on desktop can not capture many Unity Elements like dash & default compiz effects (scale) on Vivid

Desktop Recording tool used: gtk-recordmydesktop, kazaam
Ubuntu releases used for testing: Vivid & Utopic

Problem:

1. Unity elements are not visible in the video like dash & sometime right
click menu.

2. Sometime the windows (any) are not visible & appears transparent.

3. It failed to capture any default compiz effect like scale (Super+w)

4. Sometime after completing recording it saves the previously recorded
video! (until I run "compiz --replace").

For example, in this video (http://youtu.be/JQT6LTUXIe8), I opened dash,
searched for terminal & opened it. But in the video nothing is visible.

However, recording works very well in *NON-Compiz* session, i.e.
gnome-flashback (metacity).
