If you have an Ikea desk and your LED optical mouse doesn't work right
(something about the optics of the varnish) this should fix it:

Probably the varnished wood has too little fine texture for

A pad would be clumsy on my desk. I tried sanding the varnish a bit

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.

The old Logitech LED mouses are fine on anything but the Ikea desk.

My desk would look very Non-Presidential with freckles. The laser
mouse works.
