<p class="MsoNormal"><span style="font-size:11.0pt">Hello Andy,<br>
<br>
I tried to reproduce the issue with the latest JavaFX build, but<br>
accidentally downloaded an older one, openjfx-24-ea+19. With this, the<br>
flickering is still happening.<br>
<br>
However, today I noticed my mistake and downloaded the latest,<br>
openjfx-24-ea+25, and with that version I cannot reproduce the error<br>
anymore, the flickering is gone. So it looks like it's already fixed,<br>
everything is fine.<br>
<br>
Thanks for your help!<br>
<br>
Best regards,<br>
<br>
Pascal<br>
