Bad screen redrawing in Oracle SQL Developer

I have a problem with Oracle SQL Developer. When I use it on a Windows Server 2003 machine, it works fine. When I use it on my Windows 7 desktop, I get a lot of redraw problems in the query results grid when I scroll either horizontally or vertically, like so:

Edit: ImageShack was the original image host for my screenshot, and it's no longer a valid url. Since my problem is fixed now, I can't repro this. The gist is that the client area of the result grids was repainted as gibberish during scrolling.

This makes it tricky to assess the results of your queries. Clicking on the header and on individual cells causes it to then redraw properly, but it's goofy to not be able to just scroll normally. Is there any way to fix this? I am using the current version of SQL Developer 1.5.5 with the included JVM.

You need to turn off DirectDraw -- see http://tiredblogger.wordpress.com/2009/05/29/configuring-oracle-sql-developer-for-windows-7/, specifically the bit where they add the following to sqldeveloper.conf:

AddVMOption -Dsun.java2d.noddraw=true
