OldDirtBackground

This texture pack brings back the dirt background in minecraft that was removed in Beta 1.8 (title screen) and 24w09a (select world menu and create world menu). It also brings back the original Minecraft title screen logo from beta 1.4 that was changed in 1.20.

To make it work correctly, you need to disable the background blur setting by going in options , video settings , menu background blur and turn it to off. 

It should work on minecraft 1.20 and 1.21
