ADDITIONAL SYSTEM INFORMATION :
Surface Laptop Studio - Windows 11 22H2, i5-11300H, Intel Iris Xe Graphics

A DESCRIPTION OF THE PROBLEM :
When using an intel GPU on Windows, Windows using the UNIFIED style open, but do not visibly render any content.

This issue seems to be exclusive to the d3d renderer, as it does not occur when using the software renderer, or on other operating systems on the same hardware.

Setting prism.forceUploadingPainter to true circumvents the issue.

This issue appears to be similar to this existing issue https://bugs.openjdk.org/browse/JDK-8154847 (I am creating this issue to add additional information and share a workaround, as I am not a contributor)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
On windows, with an intel GPU:
Create a javafx stage with some visible content, call Stage.initStyle(StageStyle.UNIFIED), show the stage.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The stage shows up, with contents visible.
ACTUAL -
The stage shows up, but only a white background is visible.

        stage.setScene(scene);

CUSTOMER SUBMITTED WORKAROUND :
Set prism.forceUploadingPainter to true via jvm argument (-Dprism.forceUploadingPainter=true)

FREQUENCY : always
