Nope. I've used it on my warlock, FvS, Cleric, and bard since u66 came out, all too bright for me.
That's fine. I just assumed from your images of the circle at your feet that you might be Dragon Lord as well. It likely doesn't matter if you are or not though, as the issue is compounded (stacking) brightness that then blows out closeby colours to white that (depending on your display) appears overly rather bright and can cause darker areas to seem impossible to see.
The reason I can't see the issue, is because I'm using an OLED display that's also calibrated. So the darks remain visible for me throughout. However, the moment I turn my camera to the side and trigger the effect, then yes, it can blow out the effect to white and cause it to appear very bright. But if I'm looking at it from above, only the moments when I have something else stacking on top of it (such as a heal spell triggering on me) does it even temporarily increase but only marginally. Hence why I couldn't see an issue with it.
So yes, I agree that there's an issue. But I'm not sure how it can be fixed without major adjustments. Because we've seen this in place before (Memoirs teleport circles that alters the colours and brightness when stacked by looking through one side of the cylinder through the other) and that hasn't been adjusted before despite it being raised as well. But certainly asking all players to adopt an OLED screen is also out of the question, so I think the Devs will need to see what else they can do here with this info.
