JProgressBar doesn't render properly off-screen about substance

Hrm. I just found a work-around that does away with the JFrame and gets it to update properly, but am unsure of the consequences.

If I call updateUI() on the JProgressBar after each change of value, it works, Not sure why. Can't say I'm overly familiar with how that method works.

Since this is not the "primary intended" usage of this library, I would need to see a small, standalone and complete sample that reproduces this issue under the latest dev builds.

Note that the simpler the setup is, the higher the chances are that I'll get to carve out a chunk of time to take a look at it. There are a lot of moving pieces at play in the Swing rendering pipeline, and without being able to reproduce this issue I can't tell where exactly it fails.

Okay. That's going to take some time to put together.

My current project is not really stand-alone, nor is it small, but my thinking is I can reproduce this bug in a more compact form by painting to a BufferedImage and then displaying that on-screen in a more regular fashion.

So, gimme a few hours. Maybe a day.

All-right, got that done. The attached file should have everything you need to demo this yourself, except for the substance and trident jars (I assume you have them on hand, hehe). All that need be done to see the tests in action is to drop 'substance.jar' and 'trident.jar' into the 'lib' directory and then run the main jar file. Those names need to be exact.

I included the Ant script I used to build this, source code and a little readme file (kind of terse version of this message, in case you forget what you're looking at).

I tested this with the build that's marked as version 7.1.00-dev, as obtained from here, since you said you wanted it tested against a dev build. I noticed some pretty bizarre behavior from the progress bar that doesn't get calls to it's updateUI() method. Apparently it does update, but it updates incorrectly and can display some very wacky and inaccurate stuff. Most of the time it'll display as either 0% or 100%, while the text version displays perfectly fine.
