A regression test RenderingToCachedGraphicsTest.java fails when running 6u10b11 pit build, with D3D enabled in Windows vista on the Nvidia Quadro card(driver version is: 7.14.10.9686), it can be reproduced in 6u10-b07 at least.

Without d3d, it is PASS, and I run the same test in winXPpro with GeForce6600, it is PASS too w/o d3d.

The log as following:
 Direct3D pipeline enabled on screen 0
Colors mismatch!
