[Bug 1325026] [NEW] window position jumps on high-dpi screen

[Andreas E.]

Public bug reported:

When hovering with the mouse over onboard, it occasionally sets its window position again and thereby jumps upwards. 
For example: 
You move and scale onboard to cover the lower part of the screen (screen: 3200×1800, onboard position: [0,1000], size: 800x3200). When hovering the window to type a key or when changing the onboard settings, the window jumps to half the coordinates ([0,500]) and it then occludes the middle of the screen.
This happens especially when it is docked to the bottom of the screen and expanded the width, but I've sometimes also experienced it in windowed mode (undocked, with decorations).

org.gnome.desktop.interface.scaling-factor = 2
DistroRelease: Ubuntu 14.04
onboard version:  1.0.1-0ppa~t amd64 (from ppa:onboard/stable)
