After updating to macOS Catalina – when I type, macOS will randomly repeat keypresses and sequences of keypresses.
Below are some examples of some mistypes just while writing this article:
macOS => macOSmacOS Below => Below elow Below => BelBelow Some => SomeSome Some => Someome
macOS also duplicates Enter and control-sequences like Ctrl-C and CMD+V.
After updating to macOS Catalina, I also updated brew with
brew upgrade, so maybe I have some odd update in there that might be causing this issue?

I have tried multiple different keyboards. It feels like restarting the computer will make the issue go away for maybe 3 minutes and then the random key repeats start happening again.
What could be causing this and where should I be looking? I can't work like this and it's also dangerous because sometimes macOS repeats e.g. the enter-key which has already caused some confirmation-dialogs to be silently confirmed. :|
Thanks for your help!
