P: Masking panel entering values manually or via arrow keys no longer preview until Enter is pressed

Hi. In the latest version 15.1, when I change a value (e.g., from "0" to 100" or "-100"), the effect doesn't appear after entering it manually. The change only appears after pressing enter. This wasn't the case before. This makes work very difficult!

    Yes, I want to know too.  I use masks every day and this new bug is very annoying.

    What is the status of this "bug"?  Is someone looking into this?   Any idea when it will be "fixed"?

      I have the same issue on Win 11 LRC 15.1. It is nearly impossible to work on any images with mask. Update is very slow and sometime takes minutes. Any resolution?

      I have the self-same issue Windows 11 LrC 15.1 - arrow key function impaired in masking panel. A blessed nuisance! No response to remedial suggestions.

        My first report was on my Win 11 desktop. I get much the same on my Lenovo Yoga Pro laptop Win 11 LrC 15.1.

        @Anshul_Saini - another thing that doesn't work are the values ​​in "Denoise" (LrC, 15.0.1 - yes, after downgrade, W11).

        Maybe tech support will check all the options right away. After all, we pay a fortune for your software. Nobody pays us to test it and report bugs.

        I would also be grateful if you did not mark the topic as "solved".

          Look this is a very basic function in LrC.   So it's pretty obvious that most people who use this product are affected.  That being said, I hope this "fix" won't be delayed because the number of "votes" aren't "enough".

          Hi @22346234,

           

          Thank you for the clarification and for bringing this to our attention. I can confirm that I’m able to reproduce this behavior in Lightroom Classic 15.1 on macOS, specifically in the Develop > Masking controls, where manually typing a value does not preview the adjustment until Enter is pressed.

           

          I’ve flagged this issue with the product team to determine whether it is a regression or expected behavior going forward. I’ll update this thread once I have more information from them.

           

          Best regards,

          Anshul Saini

          I updated to LrC 15.1 on my desktop PC (Win 11 latest). When editing filter Exposure and Highlights and probably other fields, I usually select the field, then use the arrow keys or number pad arrow keys to increase and decrease the numbers. It is incrementing the History window with a step for each increase, even though still highlighted. It should only increment once deselected. The keys refuse to edit the numbers at times, or jump in odd amounts, generally allowing negative but not positive increases.

          I recently changed my main monitor to a 4K one form 2K, but I'm fairly sure it was fine, and the change came with LrC 15.1. It doesn't happen in the overall image editing fields, they are fine, it only happens editing filters, mostly graduated so far. Very odd. I checked my keyboard USB connections, and rebooted. I also moved LrC to my old 2K monitor (now being used a s a second monitor) but still not behaving on filters.

            Hi @9410221! Thank you for reaching out! I couldn't reproduce this issue on my Windows machine, but I can understand how frustrating it can be to update an app expecting improvements, only to find that it slows you down instead. I'll help you out with this! Could you please share a screen recording of your issue, so that we can take a closer look? You can share it via Google Drive, WeTransfer, or another public file-sharing platform. 

             

            In the meantime try resetting your preferences and see if it helps. Please try the manual method from this HelpX article: How to reset Lightroom Classic preferences

            Also, try this: in Preferences > Performance > Use Graphics Processor > Off.

             

            Let us know how it goes! 

            Noel
