I'm also running 4.6.4 (arch). This particular issue was incredibly bad when we got the first models (tearing at the mouse position) and progressively improved, but it's still not fixed.

Note that the modesetting drivers also incur in several performance hits compared to the regular xorg-video-intel. For instance, I can see libreoffice dialogs REPAINT, while inkscape works at 1/4 of the refresh speed.

This is not lenovo specific though. Intel drivers typically lag 1-2 years behind current models at the time you can consider them "bug free enough". This was true for any laptop I've been using the last 10 years.

I cannot fathom how broken the skylake driver is right now.
