pptx with background on first slide

Attachment contains:
1 slide: some small pictures. Slide contains background
2 slide: screenshot of first slide made in PP 2007 on Windows 7

reproduced in 3.3.4 and 3.5.2 on Fedora 64 bit and Windows 7 32 bit

What is interesting: in Power Point pictures shown without animation of GIF on slide pane (spare CPU consuming)

I mean during editing slide. Sorry.

I just played a bit with this. The problem is in the GIF file.
Impress cannot display it. You can try and insert it in a new presentation, it will not be displayed.
I'm closing this as Duplicate.

This issue is still reproducible in

Build ID: 616f21db9e50a77b0c02dfb123f871a742f46216
CPU threads: 4; OS: Linux 4.10; UI render: default; VCL: gtk3; 
Locale: ca-ES (ca_ES.UTF-8); Calc: group

I found something interesting... In GTK3, the background was displayed up to bea1dc5f8d17c1011cdfab1ff540f3e4b3a4d1bb, and now it's displayed without background, as in the rest of VCL backends.

Caolán, does bea1dc5f8d17c1011cdfab1ff540f3e4b3a4d1bb give you any hint why the background is not displayed now ?
