Scrolling operations on WinXP became very slow with Mustang B32 Build using OGL (with Nvidia drivers). Before B32 build scrolling was very fast and smooth, but since B32 build it's now very slow and unresponsive.

To reproduce, launch SwingSet2 with OGL and try scrolling with some of the demo panels such as the "List Demo", "Scroll Pane" demo, or "JEditorPane HTML" Demo.

- The bug seem only reproducible on Windows with Nvidia drivers and not with ATI drivers.
- Not able to reproduce on Solaris10 or Linux
