I have a Java Swing program that displays fine on Windows and on another Linux instance I use, but on another Linux platform the main window comes up, but it is blank. It is NOT the Java code but the OS configuration that is the problem; I wrote a quick and simple test program and the same thing occurs.
The buttons actually are triggered when I click where they are supposed to be, but the dialogs that come up are also empty. The Linux instance on which it does work is the same version, so that is not the problem. I've tried comparing the lists of installed packages and the env settings, but while there are a lot of differences nothing stands out as something that would cause this. I am at a loss as to what to try next.
Has anyone seen anything like this? I am not including code because as I say, it happens for Java in general. When run, there are no notices or messages that indicate anything wrong. It is running on AWS, but so is the one that works.
