I have two monitors. One in landscape and one on the right in portrait. (screenshot attached)

The landscape works fine with the splits.

The portrait view is where the problem is.

I have split into two, horizontally.

Only the top part of the portrait is "detected" it seems. Meaning, the top part I can drag an application to the top of the split(monitor) and it will fill correctly.

The bottom half though, I cannot get to work. I can't find a place to drag a window to in order to "maximize it within the split", as with the top.

Thanks for any help you can provide!

Did this ever get resolved? I am having the same problem. I do not see the 2.1 and 2.2 splits mentioned on the previous post either despite that setting being enabled.
