After switching to full screen mode, as the mouse cursor disappears the screen starts blinking, as if the backlight is blinking. About once every 1-2 minutes there are artifacts in the form of cubes or something like that.

"Screen flickering while watch YouTube in fullscreen mode: I also have this problem. Watching video on YouTube in full screen using Safari has become an issue for me. I fixed it completely. Here is my solution. System settings> Battery> Options (at the bottom) and disable (Automatic graphic switching). That's it. No more flickering images on Safari for me"

Do your Part: Inform Apple of this fix. Apple barely reads these forums as it is on their own time. So, to get the word out to them, report it to them. Apple won't get back to you directly, but the more feedback they receive on this, the more they will know what is going on, and what needs to be fixed. Apple will know nothing go this fix, if you don't report it to them.

Lots of people have this issue, seems like Apple never fixed this. There are numerous diy fixes, which should not be needed, but unfortunately are. In YouTube fullscreen, when the control bars disappear the screen starts flickering. If you move the mouse and the bars come back, flickering disappears. Something with overlays, GUI, I don't know.
I fixed it myself with an overlay app called GeekTool to always put an overlaying image on the screen. It's a transparent .png image of nothing, so you never see it. Explanation in attached image! This solution fixes it ones and for all. You will need to reboot your Macbook, the first run the image gets behind the video, so it does not work. After reboot the (invisible) image stays on top of your screen. Good luck, hope it works for you out there.
Other fixes on the net (some temporarily or at cost of battery life):
