Description Austin Riddle CLA 2009-09-10 11:36:17 EDT 
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/530.5 (KHTML, like Gecko) Chrome/2.0.172.43 Safari/530.5
Build Identifier: 1.2

If a view has a tree viewer with SWT.VIRTUAL as the style, and columnar data, everything looks fine until you scroll vertically.  Then the column data gets mashed up and various rendering problems occur like echoed text artifacts.

Reproducible: Always

Steps to Reproduce:
Use the sample project I have provided to reproduce.
The view class is VirtualView.java.
