A DESCRIPTION OF THE REGRESSION :
When using graphics2D.fill operations and drawString operations one after the other sometimes the string is not draw or drawn only partially (either not drawn at all or seemingly obscured by some pixels that have *previously* been painted in call to fill).


REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
/*
Compile this class and run it on a Windows XP box. Toggle the sun.java2d.noddraw switch and you will see that
this only happens with ddraw rendering turned on (which is the default).
My PC is a "vanilla" Dell Dimension 5000 with an ATI X300 series graphics adapter, ATI driver version 6.14.10.6476
Notice that the text "text" flickers heavily and sometimes is not painted at all. You might have to resize the Frame in order to see the effect. Also, you can play with the hardcoded constants (the random number seed or the loop count). On my PC the effect is visibly immediately using the settings below. I can provide screenshots.

RELEASE TEST FAILS:

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The drawString operation should draw its String always in a deterministic way.
ACTUAL -
Sometimes (on a repaint, e.g.) the String is not drawn, sometimes it is drawn only partially.

OBSERVED APPLICATION IMPACT:
Graphics intensive applications that use Graphics2D drawString method look broken because sometimes text is not rendered at all, sometimes it is rendered only partially.
