JDeveloper - Scrolling problem

I recently bought a new laptop which obviously came with Windows Vista (64bit).
I was facing a strange(but not new) problem with it when I scroll down in a source view or in design view, it mixes up the text in the screen and it becomes really annoying to make the JDeveloper repaint the text. It takes lot of 'Ctlr+A's and clicks to repaint the whole thing.

I've read many blogs and people suggested many things such as upgrading to JDK 6 and so on and so forth. But nothing worked.

So, here is a work around for the problem:
1)Right click jdeveloper.exe and go to compatibility tab
2)Check 'Run in 256 colours'
3)Open the Jdeveloper now.

Scrolling problem won't be there now. But all the other applications on your desktop will change their colors.These colors wil be restored automatically when you close the JDeveloper.

So, this might not be the perfect solution, but surely is a workaround.
Another small workaround is using the scroll bar instead of the mouse wheel to scroll thru the code.

I have raised an SR with Oracle and shall update here when I get a resolution(hopefully!)...
