Hi Felipe, Thanks for your prompt and informative response.
I won't be able to get access to a Windows machine for another week or so but when I do I will gladly send you some screenshots. However, are you saying that this is the first time anyone has reported such a finding? There's no existing JIRA for this specific issue? I ask because even though people tell me I am super fussy with fonts and see things others just can't see, I have observed the stated discrepancy on *every* Windows machine I have tried with JFX 8 (about 4 quite different machines) so I would be very surprised if no one else notices a difference. Thanks for the J1 suggestion but sadly I will not be able to attend this year. As for LCD on Canvas, I am very pleased that it is being addressed and even though I want it right now, JFX 9 fits fairly well with my timeline. Hopefully there will be preview releases to test in the not too distant future...
