So from my understanding, given how you've commented that it works with Xorg, you're getting the list of everything on the screen that is currently drawing a rectangle. Do you get some false positive issues with things like your window manager. What about if I made the mistake of listening to the wrong kind of music while programming (or playing YouTube in the background) -- thyme wouldn't be able to track those, right?
Also, is the name a reference to this xkcd? It's the first thing I thought of when seeing the name. https://xkcd.com/282/
