Photoshop: Blending Modes and Effects are creating arbitrary effects to underlying layers...

When I duplicate a layer and apply a filter to that layer (like Gaussian Blur), usually after changing the layer opacity or blending mode, the effect I apply will make an arbitrary change to the underlying layer I duplicated from. Permanently, without the ability to clear it through the history. I have to remove that layer - usually my retouch layer, and retouch all over again. This is the third time this has happened.

Which product are you using?
Which version?

And can you provide a bit more detail about what you are seeing?

Product: Adobe Photoshop CC

Step by Step:

I duplicate my Background layer and use the new layer to retouch a photograph.
Next, after the layer is retouched - areas cloned, spots removed, I duplicate it.

The new layer made from the "Retouch" layer is then renamed, let's call it "Blur" layer. I change the blending mode of that layer to Soft Light and lower the opacity to 21%.

Next, I go to the Filter > Blur > Gaussian Blur and set it to 12.

These steps should create a "contrasty" look - deepens blacks a little, saturates colors just a touch... etc.

Upon doing this, a few times now, the "Retouch" layer (under the "Blur" layer) renders a heavy blur effect - typically covering 90% of the whole image except for a square in the middle of the image, that represents about 10% of the whole image, which looks normal.

I turn off the "Blur" layer and the effect is still there. I turn off the "Retouch" layer and the effect disappears. I try going back into my history, but this doesn't remove the effect. The effect itself is not noted in the history, except for the moment I applied it to the "Blur" layer. Also, if I zoom out to 12.5%, viewing the image rather small, this effect is not seen and the image appears normal. But, if I save the file as a PSD at this point, the effect is still there if I reopen the file.

This means I've had to delete these layers, start all over, and retouch the image again.

Hope this helps. I can attach images or something to be more clear.

Thanks!
Joe

That sounds like you might have a video card driver issue that is failing to draw the image correctly in some situations.
