Something wrong with the Display

I’m trying to study Machine Learning Course, but somehow the display just compressed to the TOP side.
Why is that happen. Does my laptop can’t afford the loading of the simulation?
If so, is there any hardware or Internet Bandwidth requirement that The Construct suggests ?
I subscribe this learning platform every month, and I really like the way I learn ROS here.
But the whole system seems to be unstable after the Big update one two months ago.
Really need some support ! Thank you.

Same situation on Perception Lesson.
