Re: [racket-dev] Pre-Release Checklist for v6.0, corrected url
My initial reaction to your message is that this is far too big of a test case to hand over to someone else. Is there some way we can get you access to a machine that demonstrates the problem so you can make something smaller?

I can't duplicate the problem on my system, and Plot doesn't do anything platform-specific, so the bug is almost certainly in `pict', `racket/draw' or Cairo. Matthew? Sorry I wasn't clear on this earlier. (It could be that it's *possible* duplicate it on my system, and that it only shows up on the build machine because the default font is a different size, which gives the plot areas slightly different sizes, which gives the projected triangles slightly different vertices. I could look into that, but it seems unlikely. I use Plot a *lot* and have never seen this before.) If I were debugging it, I'd try to find the simplest plot that's missing a polygon. Here are the bad plots from the docs, rendered the way the docs do it (plot to a pict, then convert to a bitmap), with the number of samples easy to tweak: #lang racket (require pict plot/pict) (plot3d-samples 41) ; default is 41 (parameterize ([plot-z-ticks (currency-ticks)]) (pict-bitmap (plot3d-pict (contour-intervals3d (λ (x y) (- (sqr x) (sqr y))) -1 1 -1 1 #:label z) #:legend-anchor 'center))) (pict-bitmap (plot3d-pict (polar3d (λ (θ ρ) 1) #:color 2 #:line-style 'transparent) #:altitude 25)) I'd also try passing #:out-file out.pdf to `plot3d-pict' to see if the PDF back-end is afflicted. I don't know how worried to be about missing polygons. It could be anything from bad array management in Cairo (which could be serious) to a mostly harmless problem in the implementation of region culling or winding rules.

We really shouldn't ship until this memory leak is fixed (which I just reported): http://bugs.racket-lang.org/query/?cmd=viewpr=14264 It's making writing substantial programs very difficult, especially in Typed Racket, which seems to be affected more.
