For backends that do the object-to-device coordinates transformation directly, it's necessary to also convert the size of line width. But simply multiplying it with the matrix can also rotate the line width "vector", making it e.g. negative. So don't use just the X coordinate, use vector length for the transformation, which is ok. In fact it doesn't even make sense to treat width as a vector, because a width simply is not a vector (and for this reason it's also not actually used).
