Comment 0 for bug 1004251

When "Sync to Vblank" is enabled in the OpenGL section of the CompizConfig Settings Manager (the default setting for precise) animations, specially minimize and maximize animations, aren't smooth and stutter a lot. Moving windows, or entering the Expo mode are smooth though.

Disabling "Sync to Vblank" CompizConfig Settings Manager solves the problem. However, glxgears still informs that it is "running synchronized to the vertical refresh" so I am not sure what the "Sync to Vblank" options actually does.
