All GUIMark2.Bitmap based benchmarks show ~20% performance regression in SW pipeline starting
from build 8.0-graphics-scrum-1194. The list of benchmarks include:
 GUIMark2.Bitmap
 GUIMark2.BitmapCanvas
 JFXPanel-GUIMark2.Bitmap
 WebNode.GUIMark2-Bitmap


Here are the results of running GUIMark2.Bitmap with 100 monsters on my Windows laptop
 8.0-graphics-scrum-1193: 50 fps
 8.0-graphics-scrum-1194: 40 fps

JPA profiles show that the time spent in com.sun.pisces.PiscesRenderer.drawImageImpl has been increased by ~20%.
