FULL PRODUCT VERSION :
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Ubuntu 16.04 and Debian 9.1 stable
A DESCRIPTION OF THE PROBLEM :
Fonts are blurry on Ubuntu 16.04 and Debian 9, switching from Java 8 to Java 9 does not help, still broken rendering, see:
https://sm.bambus.ovh/javafxcompare.png
Please note that this broken font rendering occurs ONLY in JavaFX applications. Applications made with Swing or SWT or any other Java or non-Java GUI applications look good and have properly LCD sub-pixel hinting.
JavaFX uses its own LCD sub-pixel rendering which is broken on Debian and Ubuntu. It makes black text look pink or green, making small size text unreadable.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Make any program in JavaFX and run on Debian or Ubuntu, it will be blurry, sub-pixel rendering will be broken and controls will be misplaced
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Good looking fonts as in any non-JavaFX application.
ACTUAL -
Blurry fonts, with broken sub-pixel rendering
REPRODUCIBILITY :
This bug can be reproduced always.
CUSTOMER SUBMITTED WORKAROUND :
Only switching to other OS helps. JavaFX fonts look good on Microsoft Windows 10 and on some linuxes like Arch with KDE.
