Mask of adjustment layer not displaying properly

I have a picture with an adjustment layer and its corresponding mask. I can paint on the mask and everything, but when I go to the Channels palette and try to make the mask visible, Photoshop stops responding properly. It tries to paint the mask by square sections but only renders a section and then gets stuck and semi-freezed.

When I move the pointer over the image, the square sections that didn't render, get rendered but this doesn't stop Ps acting lazy. If I try to zoom in with CTRL+0, some parts of the picture appear blurry pixellated and they don't get refined (but again, they are refined as soon as I pass the pointer over them).

If I Hide the RGB channel, I can see the mask and Ps works normally again. Also, If I show only the red layer, I can see the image in a sort of BW with the mask visible and Ps works so this is some kind of workaround, but as soon as you try to show RGB and the mask channel, Ps gets stupid again.

If this helps to locate the problem, here are some data:
The image has no layers, only background. It is a RGB 2629x3951 px image.
The adjustment layer is Curves with modifications in RGB and Blue curves.
The mask is set to the default red color with 50% transparency.
Ps version is 13.0 20120305.m.415

Since a picture is worth a thousand words, here you have a pic of Ps trying to draw the mask but not finishing it. The mask should cover the girl and the floor since the curves adjustment is only affecting the background wood. (you can see the mask shape in the thumbnail)

NOTE: I edited the screenshot to remove nudity and the girl's identity (just in case)

That sounds like yet another video driver bug (not drawing correctly).

Also note that if you have a layer mask, then it's not a background, and must have a layer.

But you should also get the release version instead of using the public beta.

As I explained in the text, the mask is in the Adjustment layer, not in the background. Ps CS6 doesn't seem to have the same problem showing masks of image layers, only those of adjustment layers.

Photoshop CS6 is already released? so the beta testing is ended then?
