 First question: what do you see if running "top" (with whatever options
are needed to get all processes shown)?

 My suspicion would be that your monitor process is sucking up most of
the CPU(s), and not leaving enough for the /browser/ itself to operate.

 When remoting in, the browser is running on the host device and only
small packets are being sent/received. In this condition, display changes
can be rapid, and the only delay is in the recognition/response of the RPi
to the update request.

 Since the RPi-3 is a quad-core, you might be able to set your
monitoring process(es) to only use two or three of the cores, leaving the
fourth available for the OS and browser (at least, I'd hope the RPi-3 can
make use of the four cores -- bad enough they haven't released a 64-bit
Raspbian for it yet)
