I see whats happening now! I can duplicated this on Linux with 2.8.12 and
Windows with 2.9.2 and I'm guessing everywhere else as well. You can easily
duplicate this by zooming all the way out in Eeschema or Pcbnew and moving the
cursor to the upper left portion of the drawing area and begin zooming in. You
will see the cursor warping up and to the left until it eventually warps out of
the drawing panel. I thought I had fixed this a long time ago. The reason I
didn't see it before is that as long as mouse cursor is within the drawing area
when zooming in, this behavior doesn't happen. I think this is due to an
offset error when the drawing is zoomed way out and becomes a fraction of the
drawing window. There is a likely mismatch between the scroll bar offset and
the drawing offset when zoomed way out which causes the problem. I'll take a
look at it and see if I can figure it out.
