I have no reverted back to downgrading mutter as per previous posted and lag has subsided however I can't use NVIDIA 550 driver with the old mutter for some reason so I am stuck using intel graphics which doesn't do a great job driving all 3 screens I have. NVIDA not downgrading is a different issue though mover the freezing/lagging still exist even though mutter was fixed.
