Since a few weeks I am having problems opening documents (especially powerpoints) created with latest Microsoft Office using LibreOffice. When I have a word document open and open such a latest powerpoint, the slides only show partially (e.g. header and background are visible, but pictures and bullets won't show).

Thanks
@Parkinsond for posting above Neowin link. I tried only office and it seems that OnlyOffice on Linux does not has this annoying issues with latest M$ Office formats. I can open three powerpoints and a few word documents without issue. Although I like the super quick lanch of LibreOffice in Linux Mint (Open Office is a lot slower to open documents), I just have changed the default from LibreOffice to OnlyOffice. I will keep LibreOffice installed and check back from time to time, but I am forced to switched to the much slower OnlyOffice otherwise I can't use the latest documents from work (I am retired but still teaching my old trade on University for fun).
