Photoshop Camera Raw flashing histogram over the image
I have recently opened a RAW image in Camera Raw, as soon as the image loads the histogram is shown in its ! place, this will then disappear and show the image after about 5 secs, then if I change any of the sliders the histogram will flash over the image and the image over the histogram in the top right.

I haven't RAW in a few months so not sure if this is a bug in the latest version of Photoshop, everything else seems to work fine. Has anyone else experienced this same issue? if so were you able to resolve it?
I'm running on Windows 10 x64, dual SLI and 32gb ram.
