Giant Fuck You to Microsoft for making PowerPoint completely unable to read the text formatting of OpenDocument presentations. This is just unfair competition. No warning that it might not work, it just opens but text is broken and sometimes renders completely outside of the bounding box of the slides.

Please please please, if you're in charge of that, install
#LibreOffice alongside MS Office on computers where people need to show slideshows. It's literally free, and it will let people not using MS products to actually open the presentation and have it render correctly.

I expected this to happen and prepared a PDF in addition to the ODP file, but presenting from a PDF isn't ideal, and most people don't know they need to prepare for that.
