If your keyboard is sticking, it might be the software that you are using. Or if you are using a tablet or a phone and it's taking too long for words to spell out, you may need to reboot or clean out cache or both?

I get word salad with one of my email apps or used to get that before they updated on their end.

I noticed other posts mentioning chat rooms. I think that those apps may require frequent cache cleans, but that's my uneducated guess thinking about how chats do drain a bit on various systems.
