ADDITIONAL SYSTEM INFORMATION :
PC with touch screen
Ubuntu 20 LTS
Java 21.0.1
JavaFX 21.0.1

A DESCRIPTION OF THE PROBLEM :
ZoomEvent and RotateEvent (multi touch) events are not firing in Linux based applications. These events work fine on Windows touch screen machines and using the trackpad on a Macbook Pro


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create any JavaFX control (I've used an ImageView)
Add RotateEvent listener
Observe it doesn't fire on Linux, but works on Windows and Mac



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The ZoomEvent and TouchEvents do not fire on Linux
ACTUAL -
The ZoomEvent and TouchEvent should fire on Linux
