Saturated colors

Hello,

When I strat at first brave and play video, I get ultra saturated colors (look for screenshot); I have to restrart brave several times to fix it.
I use one 4k screen and one 1K, it only appear on the 4k screen.
I didnt managed to reiterate this bug on other brower.

Help my eyes are burning !

Is anybody there?

I found it, HDR activated on my 4k screen, when I turn it off It doesnt flash thoses colors. I will wait an update of brave or Nvidia before turn it on (It worked for 1 year before it make this sh***)
