Yup I can reproduce. Just to clarify and confirm the steps to reproduce:
1. Open Terminator with icon/shortcut and DBus on,
2. Move a non Terminator window to the front/focus
3. Repeat step 1
Second window opens in background with transparent background in titlebar (icon and text is there, though hard to see)
If Terminator has focus then the second window opens in foreground, with focus and fully rendered titlebar.
