How to get rid of white padding around point-label's text?

How do I stop plot from putting white padding around point-labels' text? Like in this example, the text isn't really legible because there's white padding around the yellow text:

(require plot)
(plot3d (list (point-label3d (vector 0 -.5 .42) "a label" #:point-size 0 #:color "yellow")
                (polar3d (λ (θ φ) 1) #:color "black")))

There is no option to disable that effect.

The code for it is here: plot/plot-lib/plot/private/common/plot-device.rkt at 2417c228b0ce4708c796b4cb0a22cc818932a605 · racket/plot · GitHub
