I can reproduce this on macOS 13.x using JDK 21.0.2 and the latest
JavaFX. If I run the PlatformPreferencesChangedTest program in
tests/manual/events we correctly detect the appearance changes. If I
first initialize the AWT toollkit as follows, then it doesn't detect
the changes:<br>
<br>
public static void main(String[] args) {<br>
java.awt.Toolkit.getDefaultToolkit();<br>
PlatformPreferencesChangedTest.main(args);<br>
}<br>
<br>
I'll file a bug...not sure yet whether it is AWT or JavaFX.<br>

There were changes to AWT in JDK 22 for macOS 14, so it might be
worth trying JDK 21.0.2. In the mean time, I'll do some testing
of this as well now that I know it is related to initializing
the AWT toolkit.<br>

<p>I am using JDK 21+35 and JavaFX 22-ea+28 to run the project
on macOS. I guess I can try upgrading to JDK 21.0.2, but I
will just assume that there haven't been many changes to awt
in that time.</p>
<p>Interestingly, I found another issue that occurs when that
call to <code>GraphicsEnvironment</code> is made/not made
where it is not possible to quit a JavaFX application via
the dock quit operation when it is minimized to an AWT tray
icon. I can file a separate issue for that.<br>

That likely means that initializing the AWT toolkit is
interfering with this functionality.<br>

I presume you are using a very recent ea build of JavaFX 22.
What version of JDK are you using?<br>

<p>Well, that is going to be a fun one to debug ... In my
application I check for a headless environment with
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices().
If you call that one before you initialize your
application, the preferences detection does no longer
update. So if you augment your
PlatformPreferencesChangedTest application with this
main method, it no longer works. Also, it throws another
exception when clicking on the fail button.<br>

<p><code> public static void main(String[] args) {<br>
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices();<br>
Application.launch(args);<br>

If you have the chance, maybe you could run the
PlatformPreferencesChangedTest application:

That might rule out that the differences we're seeing have anything to
do with the way we're using the API.
