14.3 Mail.app - Corrupted/Garbled Text When Composing Messages

Yup, exact same thing on an M1 16 inch MacBook Pro running Sonoma 14.3. This is a pretty bad bug to have slipped through the cracks. Hoping Apple recognizes and fixes it soon.

It's appearing for me in safe mode

Having the same problem. Even iCloud mail doesn't work. Using Google Mail for now. The do not have a fix for it yet. Horrible!

Since updating to 14.3 I'm having a similar issue with email text being scrambled, moved around, repeated, or overwritten so that words and sentences lay on top of each other. Any suggestions for a fix would be appreciated!

Same problem on my 2019 MacBook Pro with Intel 2.3 GHz Quad-Core Intel Core i5 and Intel Iris Plus Graphics 655 1536 MB. A real nuisance and so disappointing after having a good experience with macOS 14.2.1.

Not that it is much of a consolation, but the actual text isn't changing, just the visual in the editor. I told one of my users that it took me longer to notice because I'm a horrible typist and have to look at my keyboard so I didn't see the issue until they pointed it out. 🙂

I have the same issue with Macbook Air 2022 - M2. With the lates Sonoma 14.3 update

This is impossible to deal with and frustrating!! The text overwrites and jumbles text & rearranges it , just crazy

So, are you confirming that when Apple does a screen share, they actually see the bad text rendering?

I have reported the bug, but I will not call support and go through the agony of doing an OS re-install. I went through that 2 months ago when Apple confirmed some illusive bug that caused disk usage indexing to be corrupted. The process of doing a fresh install took 20 hours total by the time I reinstalled my apps, Parallels, made all the UI setting changes to my preferences, set up 10 email accounts again, got Time Machine setup up again, etc. My build log is here if anyone is interested. I AM NOT going through this again - I will just wait for Apple to issue an update and continue composing my lengthy emails in Word. This is really insane - I can't imagine that Apple employees aren't seeing this on their own systems.

I have posted a couple of times about this garbled text issue already. But I started seeing another 14.3 email anonymity today and wondered if anyone else has seen this. It has to do with adding signatures to emails. What I am now seeing is that after composing an email and then switching the outgoing account from account A to account B, and account B has a signature associated with it, the Mail app will place the signature in a random place within the text of the email message. This seems to only be the case if the email message also has a web link as part of the text. Anyone else seeing this?

Thank you for taking the time to do that Eric Lane. I remember having an issue a year ago where it was escalated and a higher up person was assigned to my case and I was even given a contact email and phone number they would be in touch in 24 hours. I was surprised by the attention given to me. I ended up figuring the problem out myself but the info was forwarded to engineering also.

It caused me a lot of time but also the person at apple helping me for which I was grateful since they still helped me out a lot. Sad seems like we will have to wait until the next macOS update to see a fix for this. I don't see a fix or it mentioned in the 14.4 beta in the feedback app. Glad I don't write longer emails much these days which is when it mostly happens. When I said I use a 2018 Mac mini don't know if people realized that is an Intel Mac.

Just had this issue also occur with a long text I was writing in iMessage on Mac where all of a sudden the beginning parts became garbled and wrote over the original text. Except unlike the email, when I tried to revive the original message it instead replaced with the garbled text, and now I can't see the full original message I was composing. Can't even Cmd Z either. Not good.

Thanks for the reply. For some reason, my message has been moved to earlier in the thread, at least in my browser (in fact, I posted again because I thought it had been lost). I don't know why the forum mangles threads in this way, because it makes it almost impossible to keep a coherent conversation going.

I first saw this happen some time ago when I used speech recognition to dictate emails and thought it was associated with that technology. Now, it still happens when using speech recognition, but it is also happening with keyboard input.
