I can't tell if this is a bug, or if I'm doing something really stupid, but as of last week, when I clip an adjustment layer to an image layer, the adjustment effect is simply disappearing. I am including example images which show a simple Hue/Saturation/Lightness adjustment using "colorize" over a painted layer, no blending modes used. In the second image you can see that the color simply disappears when the adjustment layer is clipped to the painted layer. This happens with other adjustment types too, like Brightness/Contrast. FWIW I just upgraded to Windows 8.1, and my the Adobe Application Manager says my Photoshop CC updates are current.
