So it is not a "green line"......It is some kind of "stuck in memory" line that does not have video on the Bottom 4 box in the 2-4-4 or in the 4-2-4 or even the 4-4-2. The Bottom most set of 4 windows always seems to pick up left over data in the empty line it has at the bottom of the box.
Quick work around to make it "go away"....Change the layout to a 1 Box....Change the source of the 1 Box to Black. Now Change it back to the 2-4-4 layout and change your Box 1 back to the source you prefer --- You can make a custom control for this :) so that you don't have to constantly deal with this while we look into how to resolve it.
