I created an application in java, specifically under java 8 using javaFx. Ultimately, the application is to be run on a terminal without a monitor connected and collect data from other parts of the system. And here is where the problem arises, for when the screen is disconnected the application gui freezes, and if I close it and restart it, all that shows up is a black application window. I use RustDesk to connect to the terminal.
I tried using another program like AnyDesk, and others, but I get exactly the same thing. The same thing happens when I poked around a bit in Windows 10 settings.
