I will also link klip from my rogue that was 4 days ago working fine, and than a klip from my warrior where is already broken. Thank you for any suggestion!

Working one: https://clips.twitch.tv/SpikyAuspiciousTireBibleThump
The circle is going red>orange>yellow>orange>red smoothly

Broken one: https://clips.twitch.tv/YummySpinele...utterJellyTime
The circle is going red>yellow>orange>red>yellow, it´s like always flushing the yellow that fades away and repeats. It´s kinda destroying my eyes and I lost my epileptic fans cuz they can´t watch my stream anymore. Please help :)
