            Bug ID: 113671
           Summary: FILEOPEN: PPTX - Textbox behind a PNG with
                    transparency show, even there is not text
           Product: LibreOffice
           Version: 4.2.0.4 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: bugzilla at mkr.email

Description:
Issue: If you open the attached PPTX, Impress shows a text box behind a PNG,
that has transparency. Other programs show only the PNG.

The slide of this file is derived from a PPTX that was created by Powerpoint
2004 for Mac (according to the properties of the original file). I edited that
presentation with Softmaker Presentations and deleted the unnecessary stuff.

The text behind the PNG is in ‚Arial Narrow‘. The text in the PNG has a
different type.

The text in the box is not the same as in the PNG. ‚y(1)q‘ and ‚x(2)p‘ are
missing in the text of the box. Impress renders in the original presentation
only slides wrong, that contain mathematical expressions.

M$ Productivity Tool shows no violation against OOXML 2007.

Issue does not come up in LO 4.0 and earlier.

Steps to Reproduce:
1. Open file


Actual Results:  
There is a textbox behind a PNG with text and transparency

Expected Results:
There should be not textbox.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
