The bug
In previous versions, the dirt background used for the credits had a considerably higher period (less repetitions were used) compared to other menu screens. As of 24w09a, if Programmer Art or another resource pack that uses a custom UI background texture is in use, the period of this texture is lower (i.e. it repeats much more often), matching that of other UI screens.
