Thanks Paul, I think your patch partially fixed bug 100065 too but still there are some shifted and flipped shapes (obsolete attachment vs last attachment in 100065).

Example is probably from MSO 2013 and can be open with that but I couldn't open it with MSO 2010. I guess rotate is right. Anyway, both works.
Not sure how this one is working and Bug 68759 not.
Comment 8 Paul Trojahn 2017-08-31 20:55:49 UTC
The test file was made with PowerPoint 2016. No idea why it doesn't work with 2010. I'll take a look at these two bugs.
