Udemy course away from home

Well so much for resuming the course away from my house. The video doesn’t show extra video options such as full screen or the video playback controls. In addition when I move my cursor over the screen, it dissappears. I tried switching the video driver to the open source one but it didn’t help. This remote computer is running Linux Mint 19.3 Mate. I installed Anaconda so I guess I can still practice.
