Mask Thumbnail Preview Not Updating as I paint
This just recently started so I wonder if I toggled something inadvertantly, but it's annoying the heck out of me!
The basic issue goes like this.
I create a white layer mask, then using a black feathered brush, I paint on that mask. I can see the effects of what I am doing on the image as expected the mask is working fine. But the small mask thumbnain in the layers panel, does not show what I am painting in real time. It remains completely white. Even though I can see the effects working.
When I stop paiting, it still shows white, even if I start painting again, it stays pure white. That is until I re-click on the mask thumbail in the layers panel. Then it suddently shows all my paintstrokes instantly.
How do I get the mask preview thumbnail to return to it's normal behaviour of showing the masking as I paint in real time?
