The same thing happens in Adobe Reader too. Although it may be OK in Sumatra, and seems to be OK in Foxit Reader, to me, it looks like a problem with the font used for the headings. Otherwise, it could be a problem with the LibreOffice PDF output.

Not only those, but many other letters too — zoom in to the ? on slide six using Adobe Reader or PDF-XChange.
I downloaded the Lato SIL fonts used by these slides and could find nothing wrong with them that would cause this. SIL are professional font develoeprs — although free, this is not a rubbish font.
I also tried a test PDF from Libre Office Writer using the Lato regular and bold fonts — again, no problem. So I suggest looking again at the source file you used to produce this PDF, or there may be a particular problem with Impress PDF output.
Try asking on the
OpenOffice Community Forums. Its not a problem with PDF-XChange as far as I can tell.
