This seems to only happen in large chats with a lot of messages, and is difficult to reproduce accurately, but having several hundred messages thrown at NVDA at one time can often lock it up for several seconds at a time. It often happens to me after I reopen a chat and more than a few new messages have come in. I realize this is sort of vague, so if there's anything I can do to log this better and send results in, I'll do it. But it is a definite problem for people who participate in big group chats, and it has happened to other people I know as well.
I'm not exactly sure how to categorize this, so I'm going to let someone more knowledgeable about NVDA's construction take care of that.
