I recently got a MacBook Pro 14 M4 and updated it to the latest release of MacOS (MacOS 26.2 (25C56)). I then tried presenting a slideshow in powerpoint that has many looping videos and noticed artifacts on the looping videos after the first or second loop. I am using Powerpoint version Version 16.104 (25121423). I have noticed in other Microsoft and apple forums similar complaints and seeing that MacOS 15.1-15.4 seem to work but not resolution after that. Just wanted to see if there were any updates or work arounds for this. I have also contacted Microsoft support but they were not much help. Just wanted to repost this issue here to get the discussion started again on best paths forward.

It seems that the recent OS update to Tahoe 26.5 fixed the issue. I tired some looped video playbacks but there is no video image degradation on my Macbook air 2025 any more.
