This Bug does not affect the Window Title or Menus from successfully appearing, but they overlay the "File Edit View Bookmarks Help" in a visible manner, making it difficult to use (especially for High Contrast). I have returned Unity and Compiz back to default settings and tried again, this bug reappears when changing the theme to either adwaita, High Contrast, or any custom theme that supports transparency of the Panel. Even adjusting transparency of Radiance or Ambiance themes in DConf reproduces this error.
