I am facing a very weird problem in Painter (Painter 11). I don't know if its because I reset all my hotkeys and shortcuts to default.

I have been working on a painting in Painter, and a little while after I changed my hotkeys, when I paint a stroke, a weird layer of wash appears and makes my painting faded. I have tried painting on different layers, but it still happens. After that if I continue painting, my brush paints like normal, but my painting is still faded. I have reverted many times to make my painting go back to its original state, but whenever I want to start painting a brush stroke, the fading reappears.

Anybody knows what is causing this to happen and how to fix it?
