Public bug reported:
So I'm not sure this is an xorg bug, I couldn't figure out what xorg is.
But I recently upgraded to ubuntu 16.10 and started seeing this bug
where my mouse will flicker and disappear when near the top of the
screen. It still works clicking-wise. It also seems to be especially
severe when using Google Chrome, where it completely disappears and
flickers the entire time while mousing over the menu uptions (i.e the
close button, the tabs etc...). However recently I noticed this also
happens when google chrome is off, though it flickers much less.
