Public bug reported:

Toggling fullscreen/maximize in demo servers shows one frame briefly at
top-left of the old size.

It's visibly moving the window to top-left in a separate frame before
resizing to full screen. This appears to be what the code does too:

            surface->move_to(rect.top_left);
            surface->resize(rect.size);

To avoid this, X (and others) use a combined "configure window"
operation that moves and resizes the window atomically. Mir would need
to do the same.
