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. 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.
