Tahoe producing constant ghost images on the screen under the cursor

The cursor on my MacBook Pro with Tahoe 26.1 continuously creates annoying "ghost" images right under the cursor that obscure just enough of the screen to interfere with operations I am trying to complete.

See attached screen shots to help illustrate what I am trying to describe.

These ghost images obscure anything behind them and when they appear when I am trying to fill in a screen form it makes it impossible to see what I'm filling in.

And they seem to be appearing near constantly now.

Here are 3 samples. I have screenshots of more examples.

Truth be told, the quality of my entire Finder user interface had been significantly degraded since Tahoe 26.1. Inexplicable lag times in certain operations. But that's a different issue and I need to be able to describe it in more precise detail for it to be comprehensible.
