      Description

      When switching from Java FX 2.2.45-b18/jdk1.7.0.45 to JDK 8.0.0-b128 I can observe a noticeable performance drop in the rendering throughput
      Clock: JDK7 ~45frames/s JDK8: ~20 frames/s
      Radio: JDK7 ~55frames/s JDK8: ~6 frames/s

      Test Case
      1. Run Netbeans 7.4 in the system environment below (low spec build-in graphics).
      2. Run the attached test program, scroll left and right to see clock or radio.
      3. Expand application window to full size.
      4. Toggle platform jdk7 and jdk8 (as set up in platform manager).
      5. Look at the frame / s counter at bottom of screen.
