I don't have an answer, but maybe some usefull questions. Is it drawing on
the side of the monitor ? Since we see what looks like the right part
(border) of the crosshatch patern on the left, I'm wondering if the gun is
over-drawing to the left.

The retrace lines inside the crosshatch patern seem to have curves, they
almost look like they were drawn by an AVG instead of a DVG. In fact, if you
look at the left most '0', it isn't fully drawn, and you can see the retrace
line pick up where the number breaks off. It's almost as if something
analog is going on as the digit starts drawing, then it starts working and
behaves normally. (This assumes off course it draws left to right :-)

I would also be curious as to what happens in regular play mode.
