Mir-on-X11 creates enormous window spanning desktop

[Alan Griffiths]

If no window size is specified using --x11-displays, or if one of the dimensions exceeds the display area then a default size is chosen that is almost the size of the display.

On a multi-monitor setup this can be enormous (and inconvenient), I'd prefer the size cropped to fit within a single display.

In theory we should be able to make the window resizable/maximizable. In VirtualBox for example that works by just unplugging the virtual output, its mode dimensions changed, and plugged in again.

Yep, is annoying, I use multiple monitors and hit this all the time
