Hi Anthony,
I do have a solution for your problem. When you click on the box to enlarge the tracker window, press the ~ (tilde) key on your keyboard to switch to full-screen mode. This will make the tracker window and the entire composition take up the entire screen, making it easier to see the tracker points and the underlying footage.
To exit full-screen mode and return to the regular interface, press the ~ key again. Alternatively, you can also use the keyboard shortcut CTRL + ALT + F to toggle full-screen mode on and off.
