UI freezes with latest ScalaFX requiring Java greater than 21 to run the JFXApp3

[sjbiaga]

Compiler version

3.7.2-RC1

Java version

openjdk-bin-25

ScalaFX version

24.0.0-R35

Minimized example

Latest ScalaFX requires Java greater than 21.
My UI works with version 3.7.1.
After update to 3.7.2-RC1, it somehow freezes after a drag event.

The communication from the UI to the background fiber is done with cats.effect.std.Dispatcher[IO]#unsafeRunAndForget from a scalafx.scene.canvas.Canvas.

Expectation

To work smoothly just like for 3.7.1.
