sounds like your Mac might be busy with some other tasks?

You could try to install the process priority helper tool, which ensures BTT gets a slightly higher priority for event processing than other apps:

Hmm possibly, but I do have the Process Priority turned on. Here's a video of it happening if that helps. Also I noticed that it's not the touchbar dot that's lagging, but the whole laptop.
