Colorspace clipping using add blend modes in OCIO v25.2.2

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

    Does anyone know if there will be a fix soon? We've been stuck with After Effects 25.1.0 for a while now...

      Hi ! 

      I have a weird issue with Display Color Space flickering when Mercury GPU acceleration is on. 

       

      I work with ACES 1.3, display color space set to RGB SDR 1.0

      I am compositing redshift passes together over a colored background with an inverted transform to match colors in ACES. 

       

      When the Mercury GPU Acceleration is on the preview is flickering because the Display Color Space is not active on multiple frames. The issue is the same when I render. 

       

      No problem without Mercury GPU acceleration.

      Ok, so I think it's the same thing as seen here :

      I related it to the "Display Color Space" flickering but it can be a simple clipping issue. 
      Also, if I set the "Display color Space" to none, or raw, and I use a color space transform effect, the issue is the same.

          Hello Adobe, I also would like to know if we can expect an update / fix soon as I am really depending on a reliable color workflow. By the way, I found out by accident, if I export a video in sRGB and import it again, when I comp this reimported sRGB Video, the whites are way too high and totally blown out, way more than normal sRGB footage. Perhaps this helps resolve the issue. Also, color correction tools to manage overbrights would be very much appreciated in ACES, with the tools we have, it is very difficult to tame some hi-key colors and whites. Thanks!
