Role colors randomly changing tones on Windows (not using Canary)

Hey there, I'm not sure if I'm the only one seeing this thing, but when I'm writing something in chat (especially with long messages) the role color tone is slightly changing from time to time. I've tried recording this, but sadly, it is not visible that way. Asked a friend of mine to take a look at this while I'm writing, he did confirm that the tone is changing, so I'm not crazy. This usually happens while I'm writing longer messages, and the color goes from the original one to a darker tone, and then rapidly gets to a lighter tone and returns back to normal. This happens very quickly but is visible with your eye if you take a closer look. And no, the colors were not changed via settings. 

Did anyone experience something similar as this one?
