Screen flickers full time and it might be even worse in local couch op mode. This has been a problem with three different Samsung TV from size 40 inch to 55 inch since Bedrock was released. It didn't occur in any platform in any older versions. But currently it affects all devices and platforms which I am aware of and have licences for. I tried it also in different households with a Samsung TV from 40 inch to 55 inch in size.

Maybe current version negotiates near 30 Hz as it is reported to cause noticeable screen flickering in a LED TV.

It is difficult to proof with videos but I am not only one who is getting feeling of nausea out of it. Something has changed in interlacing, refresh rates or something related to that. I am not very good at this. But I spent a lot of time and effort to try to understand this and this far I got.

And in local multiplayer it is maybe even more noticeable as if my relative got same nausea out of it in the same time. We both have ended playing Minecraft just because of this until it gets fixed.

If nothing has changed how signal is being processed in Bedrock then I don't understand how no other game suffers about this.
