   Thanks for the report! @mbien is correct; on some KDE systems (including the one I tested), JVM could not detect the system AA mode, and reverted to no anti-aliasing at all. Greyscale antialiasing was the conservative choice, as subpixel antialiasing looks bad if the wrong mode is selected (HRGB vs. HBGR).
   
   The interesting question is how OpenJDK managed to detect antialiasing by itself on your particular system. I don't see any recent changes in the relevant OpenJDK code, so this probably has to do with your particular setup.
   
   Do you have both Gnome and KDE installed on your system? Perhaps JDK is picking up settings from another installed window manager.
   
   If Xft.rgba has a useful value, we could use that, though, as you suggest. Could you run the following, and let us know the output?
   ```
   command xrdb -query 2> /dev/null | grep Xft.rgba
   ```
