Disappearing content in Office apps

Question

Hi

Users have been reporting an odd problem, where content disappeares from Office apps.

For example, Powerpoint may loose some text content, when user is working with a file. This text may disappeare from one user but may be visible for other user in the same file.

While user is working in other text area in a slide, text may disappeare from other text area in the same slide and user may see this happening. But if some other user opens the same file, this other user may see the disappeared text. Somehow this seems like some kind of rendering problem or something..

We store our files in Sharepoint Team Site Document Libraries (shared files) or in OneDrive (users personal files).

Have anyone else come a cross anything like this and what could be the cause for this?
