I have a group of overlay textures - all in blend mode Screen - and put a color/saturation layer over the group, then clip it to the group. When I change the saturation then, my Photoshop causes problems. The overlays change their opacity, irreversible. Zoom into image doesn't work anymore. When I delete the color/saturation layer now, all layers lose their thumbnail. But the image still looks broken. Only restarting Photoshop helps for me.
But how do I change color/saturation values of my overlay group now? I guess it's some kind of a bug. Can anyone recreate this behavior?
