Mouse Alignment in Sapphire

Hi, I've just tried editing a heightfield in Sapphire on Windows 10 using 16.05 dev 4 and had a problem - the edit sphere is positioned as if the mouse cursor is about 20 - 25px higher up.
I've made some screenshots here - the mouse cursors have been pasted on by me after the fact so may be a few pixels off, sorry I don't have software that grabs the mouse cursor too.


I also noticed that the 'point grab' tool will not use the height under the mouse cursor with a single click, but rather shoot down by a huge amount (~100 metres I think) where you need to hold on and drag it back to up to its original position. I'm not sure if this is related or a different bug.
