Quality Outreach Heads-up - JavaFX 26: Temporary Switch to macOS Metal Rendering Pipeline

The OpenJDK Quality Group is promoting the testing of FOSS projects with OpenJDK builds as a way to improve the overall quality of the release. This heads-up is part of the quality outreach sent to the projects involved. To learn more about the program, and how-to join, please check here.

Temporary Switch to macOS Metal Rendering Pipeline

On macOS, the default JavaFX rendering pipeline has been temporarily switched to Metal since JavaFX 26 Early Access build 5. This change will remain in place until October 8, 2025. The goal is to enable wider testing of the Metal rendering pipeline.

JavaFX 26 EA builds are now available for download and testing. You can share your feedback on the openjfx-dev list (registration required), through JBS or bugreport.java.com.

If you need to revert to the previous ES2 pipeline, you can do so by adding the option -Dprism.order=es2 to your Java command.
