Font Artifacts on Screen After Launching Eclipse Dialogs

[gohenderson]

To reproduce this issue open one of the following dialogs:

1) Import Existing Projects into Workspace
2) Configure SDKs (this is a part of the Google App Engine Plugin)

The artifacts persist after exiting Eclipse and the system ultimately hard locks (screen changes to white/black stripes) when left in this state.
