Hi,
I am the lucky owner of a 4K display (3840x2160 resolution)

when using on a large screen, there is an invisible line below which 
- display looks not refreshed (you have to move the window with the mouse)
- no interaction take place (ie you cannot select text, key combinations do not
work)

this line appears to be below 1440.

FYI it is used in combination with a 2650x1440 display (I don't think it has
any impact)
