Definitely not dead pixels.

I don't know if anyone has this problem as well, but it doesn't matter how many times I change my search engine, be it to google or duckduckgo, in my next session it's gonna be reverted automatically back to Bing

I'm honestly considering going back to Google Chrome because of this. Is there any way to make it fixed?

If you watch video in Edge and the bright page around the player bothers you, Turn Off the Lights has an Edge add-on. One click fades everything except the video, and another click brings the page back.

It also has a Night Mode that turns white page backgrounds dark on any website, and an eye-protection mode. It's free and open source.

It always gives me this regardless of the website. Current version: Edge 155.0.4283.48
