with poppler only StemV fails, all other values don't have any problem.

I simply uncompressed the plot.pdf and edited the 5 0 obj:
<</Type /FontDescriptor/FontName /TeX-mathx10/Flags 4/FontBBox [ 0 0 611 31 ]/ItalicAngle 86.246673/Ascent 31.5/Descent 0.78/CapHeight 0.44/XHeight 12.77/AvgWidth 24.55/MaxWidth 26.77/MissingWidth 21.44/StemH 45.44/StemV 322/FontFile 4 0 R>>

(random values) and compilation with pdftex/poppler (Debian variant)
worked as long as StemV was integer.
