Using Vaadin with JavaFX Webview Component

I’m trying to view a Vaadin webpage use the JavaFX webview component. The Java people say it is WebKit based so I didn’t expect any problems, but I’ve found several serious issues immediately.

  1. Text looks terrible. There is a large amount of aliasing.
  2. Fade effects don’t seem to work. For example a notification or the caldendar picker normally fade in/out. In the JavaFX browser this just causes a flicker.
  3. Vaadin Combo Box mouse over effects are totally broken, don’t work at all.

You can see all these problems on the Vaadin demo sites. There could be more but I stopped looking.

Does anyone else have these problems or have any advice? I’m using the latest Java 8 release.
