Public bug reported:
I see visible garbage in gutter area between screens (using multiple
monitors of different height).
It is not visible on screenshot (Screenshot from 2014-04-22
12:45:02.png), but actually visible on screen of second monitor
(Screenshot from 2014-04-22 12:45:02.png).
There is gutter area between screens, I don't know if it's feature or
bug, but second monitor shows part of first monitor's image. Width of
gutter is a few pixels. In upper area of gutter, where there's no
corresponding parts of first screen's image, there is visible garbage.
