Yes, but usually very unlikely.  There are some CJK fonts which use
bytecode extensively to position subglyphs.

In most cases, rendering with a high dpi value should produce fine
results without the bytecode interpreter.

Have you tested your font against ftview?  Does it produce the same
result?

Try a much greater dpi to avoid rounding artefacts.
