Unfocus menu

Hi everyone,
I’m making a info page based on the DiagVideoInfo for an addon. The problem is that after I call the info page ( <oninfo>ActivateWindow(1128)</oninfo>), the menu doesn’t desapear, contrary to what happens on the video (movies, series) menu. so the content is superimposed.
For now, I’m cheating and i’m using a fulscreen translucent background, the probleam is that I want to see the header and clock as clear as possible.
Already saw this http://kodi.wiki/view/Animating_your_skin, and tried the unfocus and the conditional options, and it didn’t work.

Can you guys help me? I would be grateful

Best Regards
