Yesterday, all previews in Save To Web in Photoshop became dithered, regardless of what setting (JPG, GIF with no dither) I set. I thought my monitor suddenly had changed to 256 colors. It was on thousands, so I switched to millions. Quit Photoshop, tried again, still there. Restart. Nothing.
It is really annoying and practically makes the preview useless. (Output files are good)...
This is how it looks like... notice how theres no dithering in the original (to the left).
Anybody know what might help?
