Inconsistency between database and post in Web Client

Summary
Has anyone ever had the effect that different words are displayed in the post in the web client than those in the database? Unfortunately, it doesn’t always happen, but consistently on 2 specific computers. But not on other computers. Mobile app shows it correctly.

Steps to reproduce
