    Bug fixes v2.3.0

    • CGH computation mode restriction: CGH computation within a slideshow no longer allows all present modes; it is now correctly limited to tiled mode only.

    • Slideshow transfer reliability: Fixed a transfer failure occurring during slideshow export/transfer.

    • CGH tile slider: Resolved a bug where the CGH Tile slider was non-functional.
    • Transfer and CGH calculation errors: If CGH calculations and GPU transfers fail, a detailed error message will be displayed. This is intended to improve customer support.
