The border echos and its really ugly

Also the border cant go behind other windows

I ran into the same issue re: the border being rendered on top of other windows. When both windows are floating it seems to work fine for me. But when one is tiled and focused and there is a floating window, the border is rendered on top of the floating window, even though it should be below it (because its parent tiled window is always below the floating window)
