JavaFX

JavaFX Details

JavaFX works best when it can use accelerated graphics and runs directly on a host. Running via ssh -X might work, but will always be much slower. Similarly, executing inside a VM tends to be slower.

Starting the application with -Dprism.verbose=true and -Djdk.gtk.verbose=true will show which graphics pipeline is used. es2, the accelerated graphics pipeline, is good. sw, the software pipeline, is slow and should be avoided except in very rare cases like https://github.com/ControlSystemStudio/phoebus/issues/512, where -Dprism.order=sw can be used to enforce it.

Generally, setting -Dprism.forceGPU=true can help convince JavaFX to use the accelerated graphics hardware.
