Presentation background not showing correctly

This presentation has an almost transparent background, I downloaded it and opened it in the latest version of LibreOffice and the transparency is gone.

Do you know why this is happening and how to make LibreOffice open this presentation correctly?

I tried it on my brother’s windows 7 laptop, and the presentation is showing correctly in powerpoint so the issue is with LibreOffice Impress.

I’m on Xubuntu 14.04 64 bit, running LibreOffice Version: 4.2.3.2

I have also had problems with PowerPoint backgrounds in Impress.
Try saving as an older format PowerPoint file in PowerPoint. e.g. XP/2003. This does not work all the time but it’s worth a try.
