The tree trunks will now be round.
Round Trees 1.18, 1.17, 1.16 and 1.12 is a different texture pack than usual. Although it adds new textures, it does not change all the textures in the game, but only the textures of the trees.
The textures added by this texture pack will not change the visual appearance of the tree textures, but will change their shape. With this pack installed, Minecraft trees will have a round trunk instead of a square one, which is their default shape.
If we cut down a tree and place the blocks of the trunk on the ground, they will be round, but if we treat that wood to get wood blocks, the latter will be square, as always.
