I don’t know if I am right or not, if no please provide steps to reproduce.

The issue is partially reproducing. When I used your attached document it was messy. I tried to use it in another impress document that I have, only few line texts are messed up but the autoplay mode doesn’t start.

Steps to reproduce :

1- Create a new Impress file with two or three test slides
2- Save as « Microsoft PowerPoint 2007-2013 XML Autoplay (.ppsx)
3-Close the file.
4-Open the file again.

Actual results :
The file open on the edit mode and the text is messed up.

Expected result :
The file should start in Show mode and the text keep the format.

Testing environment:
    • Operating system : Windows 8.1 Pro 64-bits.
    • LibreOffice : Version: (x64)

I'm sorry, I was not specific enough. I investigated the issue and found out that is not about the PPTS format, but about a fix in the WMF image format.

The alpha1 build of LO 6 contains a fix for images of the WMF file format.

The attached test case „Test Case WMF in Slide.odp“ is a presentation with a WMF, which is affected by this fix.

If you just open this presentation, the WMF looks right, but if you start the Slide Show („Slide Show“ → „Start from first slide“), the WMF is shown messed up.

Here is a step by step list:

1. Please open the presentation „Test Case WMF in Slide.odp“ that is attached to this bug report with LO 6 alpha1. (In earlier builds of LO 6 or LO 5 the issue with the logo is in Editing Mode and in Presentation Mode).
2. Please click on the menu „Slide Show“ and then „Start from the first slide“.
3. The Slide Show starts and the logo (a WMF image) is messed up. The image is rendered the way it was rendered before the fix in LO6 Alpha1.

To reproduce this, you need a version of LO 6 Alpha1 (fix is only there present).

In master LO 6.5+ Windows, I reproduce wrong image from ODT attachment 137676 [details] as explained in attachment 137677 [details].
I addition to Comment 7: on fileopen with OpenGL the WMF looks wrong, the same as in the Slide Show; and on fileopen without OpenGL the WMF looks fine, but is wrong in the Slide Show.
It would be nice to have that fix in 6.0, but Slide show was wrong in LO 4.0 and not wrong in that way in LO 3.6. 
I'll mark regression. Even if not , would be useful to know change.
