I have an odd problem. Suddenly, for no reason, my GUI programs are not showing any content in the frame when I run them. But they were at one point. I started creating Swing and JavaFX GUIs using Oracle's tutorials using both Eclipse and Netbeans. They worked fine. Then they didn't work in either IDE, not even the simple Hello World JavaFX that I copied and pasted. They do work on my work computer, so I know I'm not coding them wrong. But on my home computer, I only get a blank screen. I can resize the frame and set its title. For the HelloWorld project, although I don't see anything in the frame, I can click on where I know the button will be even though I don't see it, and Hello World is printed into the console. So maybe this is some sort of setting on my computer, but I have no idea what it may be. I'm running Windows 10.
I'm fairly new to programming, so I don't know if this helps, but here is part of what is written when I run it Hello World in NetBeans, which may or may not indicate what is happening.

Any ideas? I've been trying to figure this out for days.
