Comment 28 for bug 862430

The flicker/flashing issues in expo & rotate/cube have already been fixed though you'll likely not see new packages till after release of 12.04
How long after may depend on when that branch gets merged which would depend on when it stops getting revised & then hopefully approved

From a user perspective the current compiz (0.9.7.6), unity-5.10 & r-3008 do work pretty good with only a few minor visible 'glitches' on some occasion
There may be things still wrong 'under the hood' but that's nothing new
