Portrait mode lag & freeze

[tyler]

To start, everything works fine when I have two displays connected and they are both oriented as landscape.

The problem arises when you set either of the two external displays in portrait orientation, either left or right, regardless of which external monitor you set it to. What happens is the screen will not refresh the image unless the cursor is on that display, and even then it is laggy.

The second your cursor leaves that display the image on that display freezes and will not update or refresh until the cursor has returned to that display.

Another thing to note is that 90% of the time, when the cursor leaves a display that is set as portrait, the image of the cursor is still seen on the display when in reality that is not where the cursor really is.

I have attached the logs from the dubug tool as well as some videos showcasing the issue.
