Text widget flickers on XP with SWT.WRAP [message #443020]

I am using the org.eclipse.swt.widgets.Text widget in a simple text editor
I am building. Text wrap is a requirement for the editor, so I create the
widget with the SWT.WRAP option.

It works well in Windows 2000, but in Windows XP the current line of text
flickers horribly as I type. I developed the app in Eclipse 3.0, but was
able to reproduce the problem binding against the 2.1 swt.jar and DLL.

I can solve the problem by using a StyledText widget. The flicker goes
away, but with wrap enabled in the StyleText widget, performance drops to
unacceptable levels as the widget can barely keep up with moderately fast
typing.

Any suggestions? Should I file a bug report for this?

Does Notepad.exe flicker when wrap is turned on?
