Created attachment 162114 [details] The math expression
On Win10 with master sources updated today, I could reproduce this.
I noticed these logs: warn:oox:9484:9036:oox/source/helper/propertyset.cxx:136: PropertySet::implSetPropertyValue - cannot set property "IsNumbering" com.sun.star.beans.UnknownPropertyException message: IsNumbering warn:oox:9484:9036:oox/source/helper/propertyset.cxx:136: PropertySet::implSetPropertyValue - cannot set property "NumberingLevel" com.sun.star.beans.UnknownPropertyException message: NumberingLevel warn:oox:9484:9036:oox/source/helper/propertyset.cxx:136: PropertySet::implSetPropertyValue - cannot set property "NumberingLevel" com.sun.star.beans.UnknownPropertyException message: NumberingLevel C:\BLP\core\instdir\program\uno.py:487: ResourceWarning: unclosed file <_io.TextIOWrapper name='C:\\BLP\\core\\instdir\\share\\extensions\\dict-ru\\Lightproof.py' mode='r' encoding='utf_8'> for kwarg in kwargs.keys(): SvNumberFormatter::ImpGenerateCL: locales don't match: en-IL requested en-US loaded warn:unotools.i18n:9484:9036:unotools/source/i18n/localedatawrapper.cxx:1712: SvNumberFormatter::ImpGenerateCL: locales don't match: en-IL requested en-US loaded warn:oox.drawingml:9484:9036:oox/source/drawingml/shape.cxx:658: losing a Math object...
Michael: thought you might be interested in this one. Indeed, I noticed this commit: "commit 332a796366b7cb91dff41de4b9ffb17843112a3e Author: Michael Stahl <mstahl@redhat.com> Date: Thu Jan 21 17:39:26 2016 +0100 oox: import Math objects from PPTX files This is quite hacky and limited: in OOXML these are not OLE objects but occur inside text boxes, and PPT 2010 allows inserting multiple Math objects into one text box but Impress does not have as-character anchored objects, so we can't import that properly; for now only import Math if there is nothing else in the text box. Also for now only import them as children of TextParagraphContext (a:p); it's not clear what the possible parent elements could be since the OOXML standard only lists WordProcessingML parent elements :( " Calling "pMathXml = &it->GetMathXml()" each time in "if (it->HasMathXml())" block makes the formula appear.
