The OpenGL support is a bit shacky, you may either see no OpenGL drawings or they are drawn all over the window – including the menu bar. Or with CrossOver 4 you might be lucky that it simply works (here, it didn't).
Run Diamond3 and disable the double buffering in the option menu (Tools|Options ...). [In CrossOver 4 this could prevent Diamond from crashing.]
In addition, you have to disable rendering in Picture|Representation..., otherwise nothing visible is drawn (or the structures may overdraw the menubar and the sidepanes).
