JavaFX 27 Early Access build 3 switches the default macOS rendering pipeline from OpenGL-based ES2 to Apple's Metal API. Metal was introduced as an optional pipeline in JavaFX 26 under JDK-8271024, offering improved performance and better compatibility on modern Apple hardware. Developers can revert to the old ES2 pipeline using the JVM flag `-Dprism.order=es2`. EA builds are available for download and feedback can be submitted via the openjfx-dev mailing list or JBS bug tracker.
