In the main menu and while loading a world the letter 'C' of Minecraft logo is kind of spoiled . It appears to be there some very very dark black colour has covered the gap of letter 'C' of the game logo. It is sort of unnoticeable because the colour blends with the 3D shadow of the logo. It is occurring since the 1.16 Beta programme started. I have marked the issue in the photo, please zoom in and see it.
