This sounds very much like a bug in your xserver handling
XRenderCompositeGlyphs*. The fact that the fallbacks would seem to be
working correctly implies that your font configuration is functional. The
fact that the error is not a single glyph, with the error repeated implies
that the upload of the glyph data is functional. Similarly the indices
seem intact, as do the glyph coordinates. The only thing that remains is
to fix your xserver.
