McConner - it sounds like Google's MediaPipe library is not working very well on your device for some reason. I don't know why that would be - it works perfectly fine on my Galaxy Tab S4 and there is no delay like you are describing. I needed to switch libraries in order to provide much more accurate facial landmark detection (many users said the old library barely worked for them). The new library does not track individual points on a person's face, so there are no blue dots that show up anymore. The new library just provides percentages for gestures, so once the percentage reaches a certain threshold, it's likely that the person is making a particular gesture. It's much simpler from an implementation perspective (from my code) but is more complicated in terms of what is happening inside Google's code (as it uses a face mesh instead of just points).
Staggart - update to version 3.8.24. Just be aware that the face detection has a very long initialization time on Chromebooks for some reason. Google does not even support Intel 64-bit processors out of the box with their library - I had to compile it myself to add support for them, but you may see an initialization time upwards of 15-20 seconds on a higher end Chromebook. It takes 2-4 seconds on my standard Android tablets. Once the library loads properly, then there is no longer any delay. However, be aware that each time the "Test Gestures" dialog is displayed, it has to reinitialize the face detection again. I may see if I can prevent that in the future.
