[SceneGraph][HDR] Qt renders incorrectly when using scRGB

    XMLWordPrintable

Details

    • Bug
    • Resolution: Out of scope
    • P2: Important
    • None
    • 6.6.0
    • Qt RHI, Quick: SceneGraph
    • None
    • macOS, Windows

    Description

      Please use the attached small project to test. If scRGB is enabled, the rendered color will be very dull. Tested on D3D11 & D3D12 on Windows 11 and Metal on macOS. So looks like this bug is not something wrong in a specify graphics API, it may be a generic QRhi bug. This bug is making scRGB almost unusable in QtQuick.
