When grabbing a (leftmost) window in auto-tile mode, the window gets rotated with the rightmost window. Also windows width resets for both windows.
This frequently happens when using Chrome since you can accidentally miss clicking a tab and click the window border instead (which "grabs" the browser window and then rotates the windows).
