How to fix creepy aliasing when watching a video in Google Chrome?

Question

YouTube

Hello. After the next update of the chrome version on my machine, there was a problem with the fact that videos are ugly displayed in the google chrome browser, there is a terrible aliasing. If, for example, a straight line at 45 degrees is drawn in the video, then it will go with the teeth of the ladder, which is terribly infuriating, since I am doing the video. It's just terrible when the result is good, but it's impossible to look on the Internet without nausea.
There is no such problem in Firefox
Here is an example of how the picture looks in Chrome and Firefox
What I just did not try to do:
-Google in English "alissing chrome", "crappy video chrome" and so on ... it doesn’t work for me, it doesn’t help that offer there.
-Updated firewood for the video card
-Updated K-lite codek pack
-Updated flash player
-Even put firewood on DirectX
But the problem did not go away. I have a Core i5-2500K / ASRock Z68Pro3M / nVidia GTX560 hardware
Everyone says that a small percentage of people have such a problem and this is because of the video card, they advise turning off HTML5 video playback in the Chrome settings. It seems that I do what they advise, but nothing changes, and it plays HTML5 video, not flash, and the quality of the video is sickening.
Usually I always solve my problems myself and help others, but here something has already ended with ideas on how to teach chrome to display video normally, since I’m used to chrome, every time it’s inconvenient to watch video in FireFox.
Tell me what else can be done

Answer 2

I don’t know, maybe this is not your case, but the quality setting sometimes goes astray. Check that the quality is HD. The player has a gear icon. There is a choice of viewing quality.

Answer 4

As an option, you can try to install the "Disable Youtube™ HTML5 Player" extension so that instead of the built-in HTML5 browser mechanisms, the traditional Flash Player is used (as far as I understand, it is also built into Chrome, so there is not much point in updating it separately). My HTML5 player in Chrome is guaranteed to crash after some time (from a few seconds to a few minutes) of viewing, so I installed this extension so that it looks right in Flash.
