[macos14] Incorrect 3D lighting on macOS 14

    XMLWordPrintable

Details

    • aarch64
    • os_x

    Description

      ADDITIONAL SYSTEM INFORMATION :
      macOS X 14.0 / JDK 21 / JavaFX 21 / M1 Macbook Pro

      A DESCRIPTION OF THE PROBLEM :
      After updating an M1 mac to macOS 14.0 the lighting in JavaFX 3D is broken. The behavior seems to be independent of JDK and JavaFX version, and does not happen on older versions of macOS (tested with 12.0).

      See https://github.com/ennerf/lighting-issue/issues/1 for screenshots.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      git clone https://github.com/ennerf/lighting-issue.git
      mvn javafx:run

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The same result as on Windows, Linux, and macOS 12.0
      ACTUAL -
      Very large shadows in the demo, and many resulting shading artifacts in actual applications
