One more clip of something I noticed. When a window within X-Plane is open, the display draws normally. When the window is closed, the issue returns.

Having the same issue here. Video attached. I first noticed this in flight - the display was working as expected on the ground. It looks like the display is just drawing the new page on top, instead of clearing and fully redrawing.
