@petratdneska Having the Pixel 6 Pro myself, I tend to keep an eye on Pixel-related posts and to be honest it looks to me like Google has a little bit of a quality control issue with their replacement screens. I've seen far too many cases where a brand new screen - a genuine Google screen, by the way - has come with issues.
If you bought your screen from iFixit, I suggest you contact their iFixit Store personnel regarding a replacement. Their displays have a lifetime warranty so if it isn't working correctly you should be able to work with them on seeing about a replacement. Contact them by email at support@ifixit.com.
If you bought your screen somewhere else, I suggest checking the warranty and contacting the seller about a replacement.
