Weird resizing of previews on Media Recording screen

[gonzonia]

On MacOS
If the app isn't set to full screen, when you click over to the media recording screen the preview half of the screen resized very slowly.

To Reproduce
Steps to reproduce the behavior:

1. Open App
2. Make sure it's not fullscreen
3. Click Media Rcording

Expected behavior
It should resize quicker and smoother.

Video of issue attached. Sorry it's fuzzy, I had to export as 480p to get under file size limit

• OS: MacOS 15.1.1

No problem, got it!

Is this still happening? I only tried a blind fix.

[gonzonia]

It is still happening in 3.12.3

Now that I have the IDE set up on my Mac I thought I'd look into this. I see where you attempted to fix it with the overrides but when I try to debug those are never entered.

[syd711]

Right, that would be awesome. So much easier when you are on the actual operating system :)

[gonzonia]

Any suggestions on how to approach? I see what you tried to do but I'm not sure why the overrides you put in aren't working?

[syd711]

Let's go the cheap way: disable the responsive preview panel and use a fix width. Worst case is is that the user needs to scroll horizontal.

• Remove the width listeners from the panel
• Apply a fix min/max with for the preview panel in the fxml file

Okay, this is odd. I unchecked "Cache Shape" in scenebuilder for the highest level border pane on the screen-recorder-panel.fmxl. It seemed to fix it, but I wanted to verify so I got the latest on everything. Before I unchecked it again, it doesn't seem to be happening anymore. I'm going to wait until the next build to see if I can replicate again.

I found the problem. In the refresh method of the ScreenRecorderPanelController.

I narrowed it down to here.
imageView.setFitWidth(width); imageView.setFitHeight(height);

With those commented out, it works great but the image from the server is small and doesn't resize. So, the issue is definitely in how those are resizing.

I've tried a bunch of ways to fix it, but I think I'm missing a piece about how it's working because my fixes aren't having an impact.

Just leaving this as a note to look into more as an option - https://www.reddit.com/r/JavaFX/s/Q4vyETVx3A

Okay, I'm not sure how to fix this. The issue is in the refresh method.
Here's some logging I did for testing and some notes where you can see the pattern of what's going on. Part of the issue is the way the Mac is handling it. It's drawing it over and over instead of waiting until it all hits a point where it stabilizes because of the screen size. That's causing a weird jerkiness in the screen as it resizes. I'm struggling to wrap my head around how to fix it. I've tried lots of ways and some make an impact, but not necessarily for the better.
