flicker(?) from one monitor to another

I get this flickering (see gif) on every page I visit while I have twitch open on my second/third monitor. The flickering can happen on every monitor, but it stays strictly on the browser (not on desktop or when I'm playing a game). The flickering IS ONLY from twitch (in other words I see twitch on every page I visit, even on twitch if I have 2 windows with it open) , and I've never seen it from any other sites.

I use 3 different monitors; 1 is a TV 60hz 4k hdmi, 1 monitor is 144hz 1920x1080 hdmi, and my primary monitor is 144hz 3440x1440 display port.

I'm also using windows 10, and if you need my specs then just ask (have upgraded PC and issue still persist, so don't think that's needed).

​

My first thoughts were that it should be some conflict with using different monitors, but I don't really understand why it would only happen while visiting twitch then. If anyone got a solution then please help.

Not sure which flair would fit, so I went with windows.
