Automatic migration. Original reporter: "Mind Calamity"
Dragging the window inside the drag container reproduces the issue - it only gets rendered on mouse move, so when the mouse isn't moving the window isn't rendered.
Steps to reproduce: 1. Create a layout 2. Add a frame window (AutoRenderingSurface defaults to true) 3. Add a drag container to the framewindow, and a Generic/Image to the drag container (any window will do, probably)
