    Details

      Description

      There is 84% performance regression in SpiralText in hw pipeline on Windows7-high end machine.
      The performance dropped from 36.6 fps to 5.7 fps.
      Performance analyzer show that the time spent in com.sun.prism.impl.GlyphCache.getCachedGlyph from
      0.986 sec to 11.476 sec for ~ 60 pulses interval.

      Steps to run SpiralText:
      > cd tests/performance/SpiralText
      > ant
      > java -cp "JFX_HOME/rt/lib/ext/jfxrt.jar;./dist/SpiralText.jar" spiraltext.Main

      The issue is not seen on WindowsXP mid-range machine (NVidia card).
      But I see it on my Windows7 laptop with Intel Graphics-4000.

      The issue is present in latest available 8.0-graphics-scrum-1403 build.
