The existing CR that Mike filed is an umbrella bug, and the first step is to understand the scope of the problem.  Where does HiDPI cause rendering issues?  Are there non-visual problems like performance or reliability?  You can file additional issues for specific cases and link them as related issues under 7124410.


Is there a cross-platform mechanism to determine the (approximate) display DPI?  I think that would at least allow for workarounds.  For example, how far would a single scaling transform on the entire Scene in a JavaFX 2.x application go?  I suspect that JavaFX UIs would not be as much of a problem as Swing UIs.
