I just posted about this bug not 1 hour ago. I'm on a Mac OS 10.8.4, so it looks like a cross platform thing. It just kills me that something so obvious can get through the vetting process.
That is a known issue, affecting most adjustments -- we're testing a fix for it.
ah.. ok great, this bug happen to me too, but sometimes it doesnt happen
hopefully could fix it soon ,
Try the 14.1.2 photoshop cc update
Help>Updates from within photoshop cc
I have just updated to Photoshop CC and I am still having issues color correcting with curves tool. Only parts of the picture will change color...its having difficulty going back and forth from the preview to the original photo. Anything I can do to fix this?
i had this issue too.
press CTRL + K
or go to edit -> prefrences -> general
go to performance section
and press the DEFAULT button
and assign a scratch disk (c:) for example
restart photoshop and you're done probably
well that worked for me though.
The scratch disk is assigned to my HD. I don't see any other options. I clicked default and restarted and still having the same problem :/
Ashley - either you haven't installed the updates, or you have a problem with your video card driver (update it from the GPU maker's website).
