The fix 8236448 https://github.com/openjdk/jfx/pull/75 changes [MonocleApplication.staticScreen_getScreens()](https://github.com/openjdk/jfx/pull/75/files#diff-b66ff7fe72c6c5cd26003572ca901bfdL228) method code from > ns.getDPI(), ns.getDPI(), ns.getScale(), ns.getScale(), ns.getScale(), > ns.getScale() to > ns.getWidth(), ns.getHeight(), 1.f, 1.f, ns.getScale(), ns.getScale()" so the font size is not properly calculated based on the given DPI value. I left the platformScaleX and platformScaleY as 1.f because I do not know how it affects Android/Dalvik platform. On Raspberry Pi where I run JavaFX code with Monocle the DispmanScreen is used which have fixed scale 1.0 value so the app works in the same way. ------------- Commit messages: - 8243255: Font size is large in JavaFX app with enabled Monocle on Raspberry Pi Changes: https://git.openjdk.java.net/jfx/pull/193/files Webrev: https://webrevs.openjdk.java.net/jfx/193/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8243255 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jfx/pull/193.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/193/head:pull/193 PR: https://git.openjdk.java.net/jfx/pull/193
