I updated to PS version 25.11 today. When I now use the mixer brush, the normally transparent swatch in the options bar is no longer transparent, even when the brush is set to clean. It shows colors and patterns from the image which it never did before. I uses the mixer brush to mix paint already on the canvas and not adding color during mixer brush use. This is a new thing. The brush appears to be working correctly but not sure why the box is showing color and pixels. I am on an iMac 2019 running Sonoma 14.5.
When I open PS 2023, the problem does not occur.
