The new math symbols introduced in 3.5 sare poorly redered in Windows. See image attached, the symbols precsim and succsim are truncated in the lower part.
Comment 1 Olivier Hallot 2011-12-23 17:47:55 UTC
The issue is in the drawing of the nw symbols inside the OpenSymbol truetype font. Just lift the symbols a bit and adjust it with precurlyeq and succurlyeq.
