I add a video that shows the issue.
https://www.youtube.com/shorts/IYq_yHemsgA
as you can see, there is no issue until I put the mouse pointer over the
JMenu (submenu),
once I put the mouse on the JMenu the entire JPopupMenu shows the glitch.
Thanks

I can't load images unfortunantly but this is the minimum code to
reproduce the issue.
It seems that there is no way to add JMenu to JPopupMenu without
having this glitch.
Is this a problem in JavaFX?
I see non obvious errors in my code.
Thanks
Davide

Hi all,
I'm using a JPopupMenu to workaround the lack of a "real tray icon"
in JavaFX.
This is the simple code I'm using:
https://github.com/Sylvain-Bugat/tray-icon-skeleton/blob/master/src/main/java/com/github/sbugat/trayiconskeleton/TrayIconMainClass.java
It all works well until I add a submenu (JMenu) to my JPopupMenu.
This is how the tray looks when no glitch appear:
and this is the tray how looks like when the glitch of the submenu
appers:
to trigger the glitch I can simply move the mouse over the submenu
and then move the mouse over the other jmenuitem.
Any idea on why I have this error?
Thanks
Davide
