I've been trying out the patch - using quartz debug, since I don't have a retina display. Aside from occasional artifacts in theSwing controls which may well be code there that doesn't handle this case well, the only pure 2D thing that I noticed was the Texture Paint demos in Java2Demo don't seem to handle this well. The textures aren't being scaled.

Likely not our problem, rather quartz debug, is that if I switched display modes whilst quartz debug was running and we had the 2D animation running, then large parts of the display flashed, even after I quit the 2D demo. I had to quit quartz debug to get it to stop.

This only applies to a few specific applets, Most of our demos just does not work, because of that I leave it here. and the problem is not directly related to HiDPI support because you'll run into a similar bug when running with a LoDPI native resolution of, say, 640x480 or 800x600. Therefore I believe that this particular change deserves a separate CR. Could you file one please and remove the change from your current fix? Yes I'll rework it later, for now I create CR for it 8010999.

In the fix scale was added to the surface data/CGraphicsDevice /CGLLayer. This scale factor maps virtual coordinates to physical pixels. This change doesn't add support of hidpi to aqua l&f and doesn't add support of dynamic change of scale factor.
