A similar workaround, and maybe less painful than dropping to 256 colors, is to turn off ClearType (Control Panel -> Display -> Adjust ClearType text). This may also help PTC get to the root of the problem.
I didn't have any luck resolving the issue by setting the sun.java2d.noddraw and sun.java2d.d3d properties.

I have seen that. The workaround that I found was to dumb down my Windows7
display mode from True Color 32 bit down to 256 colors. It's not a great
solution but it will at allow you to work with the Workflow Admin page. And
it should also give PTC the clue they need to resolve it. It seems like the
Java 2D graphics API and Windows 7 display drivers are not happy together.
On Windows 7 to change the display mode it's : RMB on wallpaper > Screen
Resolution > List all modes

We also tried all of the java commands with no luck, and I tried the ClearType change, but got the same results. It may well be our video drivers, and going back to the earlier version of Java is not feasible. Since this only affects a hndful of folks(there are only 4 of us who are authorized to use the Workflow Manager), we found a workaround by consoling in to the server, and doing our work there on the workflows. We just found it strange that the Workflow Manager display has problems, yet the Process/Routing displays from the details pages work just fine.
