Comment 3 for bug 1488417

unduping for the moment, after some discussion with anpok, while this is similar we're not totally convinced it's the same

@duflu also, your are welcome please try this - specifically notice that if you move the mouse completely horizontal, the mouse will stick in a position that is inconsistent (e.g. sometimes sticks at a position further left or shorter left from the right edge than the previous time)
also, when the mouse "sticks" to a position while moving completely horizontal to the right, keep moving horizontal to the right, then move completely horizontal back to the left....the distance you travel back to the left is ~ the same before the mouse is "picked up" and "unstuck" giving it a feeling the position is changing for the mouse, however not rendering correctly.

note this is silo 0 where unity8 is doing the render - using the mir relative mouse events
to install
flash nexus4 with --channel=ubuntu-touch/rc-proposed/ubuntu
then install silo 0, unfortunately the silo is dirty holding back unity8 (atm i think) - so even if you install using ctrain tools you'll need to dist-upgrade
so....citrain device-upgrade 0 <device pin/password> , then apt-get update, apt-get dist-upgrade
