Brush tool, when I click & paint, the screen in Photoshop goes white until I unclick

[#1]

Whether I'm using my Photoshop CC 2019 or 2020, when I use the brush tool to paint over my image or even the heal tool, I'm having an issue with the screen in Photoshop going white when I click. Which makes this impossible to see what I'm doing. When I unclick the mouse, the white screen goes away and I can see where I just painted. So It's not like the tool doesn't work, just can't see what I'm doing.

Any help would be great!

Thanks JJMack. Now that I think about it, it started acting up after I updated to the Big Sur. Typical. Hopefully, Apple & Adobe can correct the issue soon.

Thanks so much for the quick response!!

I had this issue too. Try resetting all of the preferences and then restarting Photoshop. It worked for me!
