White box and error message in OS X.

[LeifAndersen]

I am running the latest version of OS X (El Capitan), and I try to make the following pict3d program:

#lang racket

(require pict3d)

(sphere origin 1/2)

When I run this program, i get a white box, and the following error message pops up in the DrRacket GUI error box.

OpenGL error in procedure glClear: Error code 1286.

Same for me, just a white box with all controls, but even no error.

Mac OS Sierra 10.12. The result of:

#lang racket

(require racket/gui
          sgl/gl)

(define (get-graphics-info legacy?)
   (define config (new gl-config%))
   (send config set-legacy? legacy?)
   (define frame (new frame% [label "Test"] [width 100] [height 100]))
   (define canvas (new canvas%
                       [parent frame]
                       [style '(gl no-autoclear)]
                       [gl-config config]))
   (send frame show #t)
   (sleep 1)
   (begin0
     (send (send (send canvas get-dc) get-gl-context)
           call-as-current
           (λ ()
             (list (glGetString GL_VENDOR)
                   (glGetString GL_RENDERER)
                   (glGetString GL_VERSION))))
     (send frame show #f)))

(get-graphics-info #t)
(get-graphics-info #f)

Is:

'("Intel Inc." "Intel Iris Pro OpenGL Engine" "2.1 INTEL-10.24.45")
'("Intel Inc." "Intel Iris Pro OpenGL Engine" "4.1 INTEL-10.24.45")

Got it working with @jeapostrophe's version of pict3d. First time with this version Racket was unable to get OpenGL context (like in #10), but launching/re-launching and then installing/reinstalling helped, now it works!
