Comment 98 for bug 763005

To the best of my knowledge, the right direction would be to start by subscribing to these bugs, all of which are potentially related to compiz stuttering...

Bug 888039: Compiz performance degrades (begins stuttering) over time

Bug 861061: [regression] Unity makes 3D apps run much slower:
Actually, Unity makes all apps stutter and slow. It's mostly noticeable in 3D apps where you care about and often measure framerates.

Bug 880707: [regression] Visible tearing occurs even when "Sync To VBlank" is enabled, but only when Unity is active:
It might not sound related, but the fix we're working on for 880707 should reduce stuttering and improve compiz performance in general.
