I don't know if I've run into a bug or I'm doing something wrong. I have a
GEF editor in which I have antialiasing turned on. Everything is working
fine except for my thumbnail view, which is inside an
org.eclipse.ui.part.Page. When antialiasing in the editor is turned off,
the thumbnail looks fine, but with it turned on, the background in my
thumbnail is black. Has anyone else see similar problems?
