I see. Have had the same issue.

This is still present in 25w45a. I believe this is caused by the new block-face “anti-aliasing” that was added in 25w44a, as evidenced by all solid block textures no longer having jaggies. This should ideally be toggleable, but there should be a fix for players who wish to have anti-aliasing enabled and mipmaps not.
