The issue related to ".pptx file graphics/colors inaccurate conversion in
Impress" has been reproduced in the last OpenOffice version.

When opening a *.pptx using OpenOffice Impress, shapes (circles, rectangles,
etc.) are moved upwards, 'line arrow' or 'curve arrow' are displayed like
'elbow arrow' and font colors are missing, so 'Automatic' font color is applied
to all the text. Please, see the attachment: attachment 86772

This has been compared against LibreOffice Impress, and using LibreOffice the
shapes (circles, rectangles, etc.) are only slightly moved rightward,
'line/curve arrows' are displayed properly and font colors are not missing.
Please, see: attachment 86773 and attachment 86774

Additionally, it was noticed that LibreOffice allows us to save files as *.pptx
while OpenOffice only allows us to save files as *.ppt; I don’t know if the
fact that LibreOffice allows to save files as *.pptx has some relation with why
LibreOffice open *.pptx files with more accurate conversion, but the user
experience with OpenOffice could be improved if there is a more accurate
conversion by trying to keeping font colors and decrease the fact that shapes
are moved forward.

I second [email protected]'s comment about a message telling us that
‘there is likely to be compatibility issues when opening non OO file’ will be
helpful, but if there could be a way to have a better conversion when opening a
*.pptx file with OpenOffice Impress, will improve the user experience
considering that when users are looking for presentations in internet as a part
of any research, the presentations use to be PowerPoint files.

A workaround that was found in order to open a PowerPoint presentation (*.pptx)
with more accurate conversion using OpenOffice Impress was: saving a *.pptx
presentation as *.ppt, and then opening the *.ppt file with OpenOffice Impress.
(Could be other issues about opening *.ppt files like the one mentioned in the
issue id: 121973 though)


Please, see below the steps to reproduce the issues and the workaround

REQUIREMENTS:
=============
- Windows 10 enterprise OS
- Have .pptx presentation that contains:
   * Shapes (e.g. circle) that encapsulate any text 
   * Line arrow or curve arrow
   * Different Font colors
As example see the attached file: Test_conversion_in_Impress.pptx (attachment
86775)

STEPS:
======
1. Download the Test_conversion_in_Impress.pptx file
2. Open the pptx with Power Point and notice that the presentation contains
different font colors, shapes and arrows
3. Close the pptx file
4. Open the pptx file with OpenOffice Impress
   - Select the .pptx file
   - Right click on pptx file -> Open with -> Choose another app -> OpenOffice
Impress
5. Notice that shapes were moved upwards, font colors are missing and elbow
arrow is displayed instead of line/curve arrows.

WORKAROUND:
============
1. Open the .pptx (2007-365) file with PowerPoint
2. Save as .ppt (97-2003) file
   - File -> Save as -> Browse -> Save as type = PowerPoint 91-2003
Presentation(*.ppt) -> Click 'Save' button
3. Close ppt file
4. Open .ppt (97-2003) file with OpenOffice Impress
   - Right click on ppt file -> Open with -> Choose another app -> OpenOffice
Impress
5. Notice that shapes are not moved upwards (at least it is not noticeable),
font colors are kept and line/curve arrows are displayed properly.
