I'm running Photoshop CS6 64-bit on a Toshiba with Windows 8 and a AMD Radeon HD7670M graphics card.
Sometimes, out of the blue, the image I am working on itself turns black. Not the whole screen, neither the whole Photoshop window: just the place where the image itself is, within the Photoshop workspace. This happens every now and again, but most often anytime I move the area where I am working, ie. when I scroll, zoom, etc. Although this is solvable (by scrolling a bit more, for example), it is also really annoying.
Is it a problem with Photoshop, with my graphics card, or with something else?
And how can I solve this?
