ADDITIONAL SYSTEM INFORMATION :
Debian 12.7 (Raspbian)
Raspberry Pi 4B / Alwinner A72 / aarch64

used JavaFX runtimes from AzulZulu, temurin, openjdk / openjfx, gluon
version 23.0.1, 22, 21, 17

A DESCRIPTION OF THE PROBLEM :
For proof of concept we try to port a library of jars using JavaFX previously run on windows to linux.
GUI working fine on x86_64 but not on aarch64.

Please refer to "Actual Result" for details.

We've had the same (visually at least) behavior on x86_64 with openjdk 17. Works on x86_64 with version 22, 23, 24ea (other not tested).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use any jar containing custom JavaFX controls, or animation, and try to run on aarch64, i.e. Raspberry Pi or similar.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Same rendering as on x86_64
ACTUAL -
Window size and position correct.
Displaying static images and text works, although position and scaling is off, animations (blend in of image) do not work.
Controls do not display at all -> black / blank window

CUSTOMER SUBMITTED WORKAROUND :
n/a.

Would love to help debug the root cause, and provide required logs/info.

FREQUENCY : always
