Slider Controls in Brightness Contrast and Vibrance Stopped Working

[Gemma5D06]

Hi,

So Fresh install of Photoshop on a new PC, and installed all my Previous Plugins, but for some reason the Brightness / Contrast and Vibrance under Image adjustments is not working (It's not giving me a live Preview), as in if I slide the sliders, the picture does not update. The only way I can get it to update, is by doing a slider adjustment and then untick and retick preview which is a pain. The other odd thing, is if you look at the slider bar for Contrast, its not in the middle. I'm not using layers, and I've tried Resetting Preference on Quit but run out of ideas now.  Same problem for Vibrance as well, but all other adjustments work, like Levels etc.

Thanks

@Gemma5D06 I assume you're doing it from image > adjustments, does it work if you use the adjustments panel or the create new fill or adjustment layer option

[Gemma5D06]

Yes, it works if I do it as a Adjustment Layer option fine, so that's a good workaround for me, just not working when I click Image Adjustments.

Thanks very much for your reply

I never use the image > adjustment option, as that's a destructive method, unless your layer is a smart object of course.

The image > adjustments options are working on my system with Photoshop version 26.8 on Windows 11 BTW

That's really not a great way to end a trouble report Ged. 

I am having the same problem with Image/Brightness/Contrast not working using the preview.

Using your work around with Adjustments bypasses the whole problem and there has to be an underlying issue that Adobe programmers need to figure out because I would bet 1 Dollar this issue is or will lead to bigger problems down the road. 

I've gone through checking to see if my GPU is running and it obviously is because the work around you describe works so it wouldn't work if the GPU wasn't working.

Come on...... figure out the problem.

Thanks

Actually Ged your work around is changing all the layers of an image I am working with, not just the new layer that I am making in an effort to preserve the original image.

It's broken.... it's not my GPU, it's not my driver... it's obviously the latest downloaded update because I have never had this problem before.
