I'm using a Macbook Air Rev. A with OSX Snow Leopard. I've noticed a number of problems with my JavaFX applications.
1) The applications run very slowly. I've run the same applications on my PC which has poorer specifications than my laptop and on the PC they're blazing fast without artifacts and on the mac they crawl.
2) Text artifacts - sometimes characters are scrambled, sometimes characters are missing. Normally the app renders fine and then a split second after launch the characters get scrambled. This varies between builds even if I don't change the code.
3) Sometimes if the content is larger than it's parent window (of if a scrollbar is used) the contents gets inverted (mirrored and turned upside down).
I think this might be a problem with graphics drivers and may be connected to this issue (http://javafx-jira.kenai.com/browse/RT-17841). I've tried running ensemble rendering with j2d and it's faster than with hardware acceleration. If you had any advice about how I could change my system configuration to resolve this problem I'd be very grateful.
