After 1.20.4, tipped arrow projectiles no longer use the respective "tipped_arrow.png" texture, instead using the regular arrow texture.
Here, I have used a resource pack (provided) that changes the tipped arrow texture to be entirely red for demonstration.
As you can see, in 1.20.4, the tipped arrow is red as expected.
[media]However, in 1.20.5 and onward, using the same resource pack, the arrow simply uses the same texture as regular arrows.
