I have issue that when converting word DOCX files with word-interop to PDF it happends ocassionally that file does not convert well - some part of text is missing.
In my current situation there is missing one text bubble with two lines of text.
I have created a mini test application that converts test.docx to pdf and I see that problem appears on two machines "Windows Server 2008 R2 Standard" with "Office 2010".
Edit: On "Windows 7 Professional" with "Office 2013" : problem is present on two PC's, and everything works OK on one PC (mine workstation).
I'm looking for some leads where to look for solving this problem.
Edit: Here is a image to show what do I mean by "missing one text bubble with two lines of text".

Middle: Interop conversion output.
Right: manually saved DocX to PDF in Word
