Hi Felipe, Thanks for the info.
Is kerning planned for a Java 8 update or will it have to wait for 9? Or 10? One more thing I have just noticed is that the way the text is rendered in a Text object with LCD font smoothing is quite different from a Label (with the Text object looking better and closer to native text). While I concede that the "better" font rendering I thought I observed in WebView is probably an illusion, there is definitely a difference between Text and Label (at least on this machine). Why would that be? Are they rendered differently?

Sub-pixel positioning ( > https://javafx-jira.kenai.com/browse/RT-14187 ) Yes, if all goes well RT-14187 will get fixed for FX8. Notes: -On Mac we already have sub-pixel positioned glyphs. -LCD text we also have sub-pixel positioned glyphs. -The main one that I feel we are missing is grayscale text for Windows. -It is very unlikely we will have time to do anything for Linux this time around. 2. Kerning ( https://javafx-jira.kenai.com/browse/RT-7472 ) Not target for 8. 3. Is it just my imagination. Webview node and text node both use the very same drawing code in Prism. I would not expect to see any difference... I hope this helps, Felipe On Aug 27, 2013, at 3:42 AM, John C.
