As others have written, vim has changed copy+paste defaults some time ago. Some even call this changing defaults "they broke copy+paste" ;). One easy thing you might want to check is if this also happens in neovim. Neovim did not make this copy+paste change, and it might behave subtly different. It's quick to install and check. /ralph
