Hi, With the changes introduced in the fix for RT-27960 ( https://bugs.openjdk.java.net/browse/JDK-8098184), the hidpi support on Android is broken.
As part of the changes in http://hg.openjdk.java.net/openjfx/8u-dev/rt/rev/670ed25ed138, we introduced a getScale method on NativeScreen, and the result of this method was used in the constructor of Screen (See MonocleApplication.java). As an example, on a Nexus 5 the getScale() would return 3.0, as the device has 1920x1080 physical pixels but we use a Scene with dimensions 640x360. I'm not sure how to map this getScale() to the new getPlatformScale() and getRenderScale() though? - Johan
