When I move a slider, nothing happens. I can only see the change after I hit apply and the open the window again. It only happens with sliders. If I choose a tone-profile or wb setting from the drop down menu, I can see the photo changes instantly. Same with pasting settings. Graphics acceleration is turned off ---

Not seeing that here on W10. There’s sometimes a small delay in seeing the effects of the sliders, but they do work for me. ---

Are you on the latest version of NLP (v3.1.1)? Are you on the latest version of Lightroom Classic? Is this happening in the Library of Develop modules? Does this happen if you go to the “advanced” tab and change the color process to “Classic” ---

I am using the latest version of NLP and version 13.0.1. of Lightroom Classic. It’s only happening in the Develop module but it does not happend at all if I choose the “Classic” color process ---

Nice to see I am not the only one having this issue ! Keep the color process to Classic indeed solve it but the Refined one is so much better I have to invert in the library pannel, which is painfully slow… ---

Can you try upgrading to the latest version of Lightroom Classic and see if that fixes your issue? Also, does it work in the Library Module? ---

I don’t have this issue with the current NLP 3.1.1, **LrC 13.4** , macOS 14.8.1. \_\_\_ Note that I’ve also tested with other versions of LrC and macOS a while ago. I don’t think I’ve seen the issue in the last (10?) months.
