You can try it with a newer version of OpenJDK + JavaFX: https://www.b4x.com/android/forum/threads/update-openjdk.140167/post-887747

Maybe it will solve it.

i download - JavaFX SDK + jmods: https://gluonhq.com/products/javafx/
but cant find OpenJDK 17.0.9 for linux to download.

Download the more recent OpenJDK you find. It doesn't need to match the JavaFX version.
