Thanks, that makes a lot of sense. It was pretty straightforward to start like you said. I did run into an issue with the GUI's background not displaying correctly as shown in the image below, but I found out it was more of an issue with my specific setup (M1 Mac, docker, & XQuartz) than with the visualizer itself.

(Took a photo of my screen because screenshots didn't capture the issue.)

I discovered from this issue thread that I could fix it by adding the following to run_viz_debugger of the run-tests.py in the handout:

    command.append('-Dsun.java2d.xrender=false')
    command.append('-Dsun.java2d.pmoffscreen=false')

Anyways, I'm excited to poke around with the new visualizer. I do think that the collapsable windows in Oddity were nice, and they made it quick & easy to inspect an entity and see all of its state. I think a similar mechanism would be great here as well instead of having to scroll to see all of the information in each of the panels.

Re: visual glitches, please feel free to open up an issue! I want to fix these issues and have already done some hacky things on startup to include platform-specific fixes.

Re: state inspection, everything is expandable! Just double-click. Maybe there should be better docs or maybe the UI should make that bit of feature discovery more obvious.

@andrewnguyen92 if you comment out these lines in DebuggerWindow.java

        if (!runningInWSL()) {
            System.setProperty("sun.java2d.opengl", "true");
        }
        System.setProperty("sun.java2d.noddraw", "true");

but don't do anything else like appending those extra parameters in run-tests.py, do you still get those visual glitches? I'm thinking at this point that trying to enable opengl is more trouble than it's worth.

That sounds good - I'm not sure how many other people are running dslabs with a similar setup as mine, but I'll write up an issue and post my fix in case anyone is. And yea I still get that glitch even with those lines commented out.
