Sample PPT
The attached PPT, which has notched circular arrows, is slide 6 of attachment
199209 from bug 165258.
Open it in Impress, save as PPTX and reopen, or open the result in PowerPoint.
=> One of the arrows in each circular shape is very off.
While this never was OK, the shapes in the converted file used to look worse:
1. for a long time, the arrows were pointing all over the place,
2. then it became the current look: only the last arrow in each circular shape
is shown exaggerated,
3. then the last arrow turned into a circle pie shape,
4. then it reverted to the previous look with the exaggerated last arrow.
The shape mostly becoming good (2.) is due to the following change in 7.4 /
7.3.3:

And this is where the last segment changed back into an arrow (4. = 2.) in 25.8

"tdf165262 PPTX export: fix shape export regression"
(the relevant part is adding "mso-spt100" to constAllowSet in shape export
code)
In the unzipped PPTX, ppt/slides/slide1.xml has 'a:path' elements like this:
<a:path w="14850" h="8738">
Changing all of them thad had w/h other than 21600 to 21600, and rezipping the
file produces correct result:
<a:path w="21600" h="21600">
