<p>I experimented with this myself and created the draft PR
<a class="moz-txt-link-freetext" href="https://github.com/openjdk/jfx/pull/2045">https://github.com/openjdk/jfx/pull/2045</a>. If you like, you can try
it out. I think at least that this is the issue you described.</p>
<p>I haven't evaluated all the consequences of this yet and only
tested it on Windows. But there it works as expected for me</p>

<div dir="ltr">Hi,<br>
<div><br>
</div>
<div>Our application has traditionally used
StageStyle.TRANSPARENT to enable a fully customizable
stage. </div>
<div>This allows users to set custom backgrounds and adjust
the window's opacity freely, leveraging our powerful
personalization features.<br>
<br>
After the release of JavaFX 25, we want to migrate to
StageStyle.EXTENDED so that <br>
we can use native window decorations and no longer need to
draw window shadows ourselves.<br>
But using StageStyle.EXTENDED creates a stage with a white
background, which prevents us <br>
from setting the window's opacity.<br>
So is there any way we can make the stage background
transparent while using StageStyle.EXTENDED?<br>
