The transparent part of png icon shows totally black

[hp7hao]

Hi there, I encountered something strange. The icon can't be displayed correctly. My png icon has a transparent background, but the transparent part is totally black I added -Djdk.gtk.version=3 to run my app and the menu correctly adopted gtk theme.

In order to narrow down what is causing transparency issues, can you run my test examples?

Can you also run your example without javafx?

I don't know if KDE is causing issues, or if it's javafx.

Fixed!

I'm not sure exactly what was causing the errors, but with all of the work done (for other fixes), this is no longer an issue.

Thank you for the bug report.
