--- Comment #14 from Martin Peres <martin.peres at free.fr> ---
So, you are obviously using the Intel DDX. I tried replicating your setup on my
desktop PC (hsw-gt2) with intel the same xorg options but rendering was solid
on both kwin and mutter. Same on my ivybridge laptop.

Now, I wonder what the heck unity is doing because it looks like DRI3 is never
enabled (based on the rendering). You should actually check that you are indeed
using DRI3 by running the following command:

LIBGL_DEBUG=verbose glxgears

I suspect that mesa or the intel ddx has not been compiled with dri3 support
and you just get never get it, despite asking for it.
