OnlyOffice 8.0.1.31 (x64) vs LibreOffice 24.2.1.2 (x64):
Which is better at compatibility with some PowerPoint 2007 features that probably noone besides me cares about?
The file I used: https://geocities.ws/yrex/PPTCompatTe...
This video was supposed to end with "LibreOffice won", but then I did another test on more "normal" content where OnlyOffice fared better, so I guess it depends.
What's the conclusion? Probably to not rely too much on special effects if you care about compatibility.
