BUG: Corrupted highlight rendering / color glitching on DNG files

What happened?

When opening a .dng file in RapidRAW, the overexposed highlight areas (specifically the sky in the background) are rendering with severe, jagged white blocks and strange color glitching (magenta/green/blue edges). It looks like a processing error with clipped highlights rather than a smooth transition to pure white.

What did you expect to happen?

The overexposed sky should render as a smooth transition into pure white without harsh jagged edges or glitching.

How can we reproduce this?

  1. Open RapidRAW on macOS.
  2. Import or navigate to the specific .dng file (DSC08950.dng, 6336 x 9504).
  3. View the image in the main editor window.
  4. Observe the rendering in the blown-out highlight regions.

Operating System

macOS Apple Silicon

RapidRAW Version

1.5.5
