Windows 10: Update - KB4464218 (OS Build 17134.286) ; It broke my screen contrast

I've tried a couple different things but this update has broke my contrast, but only when a picture is moving.


I know because i've tried taking a screen cap of the problem, but when i stop the video or pause the game the image fixed itself and, no, i can't record a video. Sorry if i can't provide a picture.


Because that's it, everything that has a border and is moving suffers when there is contrast. In a video i was watching earling the background was dark but the person was wearing a white shirt. The border of his body, mouth, anything that's not an unique texture and has a color contrast with something else in the video (or in any moving picture on my screen outside this example) sends this milliseconds of rainbows. This everytime there's contrast.


It's kinda of a big problem, because some people might have some eye-related problems that could be troubling depending of the severity of the contrast.


And no, yesterday was everything fine, both the same videogame, both the same video service. Thank you for your attention.
