On the community.letsencrypt.org forum there’s a little problem with the message body getting resized (smaller) horizontally while scrolling down and up through messages. I noticed it last night and PM’d one of their engineers, @jsha. He asked me to post it here for him. Here’s the screen shots. I only had to scroll down a little for this to occur. It also occurs as I scroll from one reply to the next.
Actually @JimPas, the theme that you are using (Vincent) is one we installed custom for ourselves a while ago in order to offer dark mode. I’ll see if there’s an update for Vincent or if we can work around in some way.
