Digging deeper into my own code, it appears that there are several areas where I need to account for screen scale within the application's code itself (i.e. I use coordinates from mouseEvent to set the layout of some elements, and these are not snapped), so it probably safe to ignore these issues in the context of the PR. ------------- PR: https://git.openjdk.java.net/jfx/pull/308
