Hi,

Just upgraded to 25.2.2 and I am having a strange issue with adding layers its like it randomly clips or switches color space from one frame to the next. Only started happening after upgrading AE and NVIDIA.

The screenshots are from the same project just different frames, as you will see it also affects the scopes. Only effect used is 'Fast Box Blur'

Switching to 'Software Only' fixes the issue

    I am getting an issue when using add blend mode in aces, it makes the comp clip at 1, seem to be present in the beta too.

     

    1. 25.2.0

    2.Windows 11

    3. Project file included

    4. It clips the image, the expected result if a aces linear work flow

      Here is a better representation on the scopes with the signal clamped. Its clearly clipping on 1, this happens randomly as I scrub the timeline.

      Thanks for reaching out.

      Do you mind sharing your system specifications and details of the media? If possible, please share a sample media and After Effects project file for testing. Feel free to share via DM if you do not want to share publicly.

      Looking forward to your response.


      Thanks,
      Nishu
