One of these days I went to play with some friends, but my Minecraft had automatically updated through the Microsoft Store to version 1.17.20 (which I later found out to be the beta version, even though I wasn't part of the beta program)
I went to the app store and tried to update again, and to my amazement Minecraft went back to version 1.17.10, so I was able to play with my friends, who were on 1.17.10.
I noticed a glaring difference in the appearance of water in the game. On the outside, the water was normal, with a normal texture, but when submerged, the water that used to be very clear and easy to notice the presence of mobs, became very opaque, with a lot of "mist". I leave some photos for clarification. I notice that I went to many aquatic environments, with different waters, from warm, cold, shallow and deep waters and all had the same problems.
