I have a pile somewhere.  Does that count?

Not enough contrast at high spatial frequencies.  Newer mouse probably
has higher resolution optics, so it sees the wood grain better, and
maybe the sandpaper frosting a little.

Does the old mouse work OK on a mouse pad?  Or on a piece of white
paper?  If so, what could work would be a random pattern of little
paint dots in or on the varnish.  Like from an airbrush too far away.
