tiling windows form right to left flashes gray screen

[Ezra Sharp]

Using Ctrl + Super + left/right arrow keys to tile windows on the left or right, when the window is on the right and you switch it to the left the screen with go blank for a second with a dark gray background.

Works fine from left to right, only on right to left.

Hop-fully you can see it on the video, the screen recorder or my video playback has really bad performance :(
