Known Issues

  • After initiating Apply Develop Settings in View mode, the image disappears until the Develop settings are applied.
  • IPTC Getty metadata is not detected in images converted from a previous database if they do not have any other IPTC metadata. Use “Rebuild Thumbnails and Metadata” on these images to detect the IPTC Getty metadata.
  • AI Super-Resolution and AI Denoise cannot be run on the GPU on a computer with less than 4GB VRAM.
  • AI Super-Resolution and AI Denoise can switch to the CPU on a computer with 4+ GB VRAM if the system is under heavy load.

  • Batch AI Super-Resolution and batch AI Denoise only show the preview for the first image.
  • Some H.265/HEVC videos with HDR enabled cannot seek in View mode. Moving the play head will cause the video player to freeze. The application will not freeze, and you will be able to switch to another file or leave View mode to recover. We have reported this issue to Microsoft as it appears to be outside of ACDSee’s control.
  • GPS metadata cannot be saved to HEIC or video files on the Map pane. These files cannot be dragged onto the Map, and files with GPS metadata will not save any changes to position.

  • When using Sky Replacement on two layers of different sizes, the smaller layer’s sky will bleed outside of the selected layer.
