[144pt at which resolution? It's neither 72 nor 96dpi...]

I have absolutely no explanation how you get these results, and I
can't repeat it on my GNU/Linux box.

My suggestion is that you write a small GNU/Linux command line
application which uses exactly the same font loading setup as in your
OS/2 driver. Be sure to compile FreeType with activated debugging
support, then say
FT2_DEBUG=any:7 your_command ... &> your_command.log
Compile and execute the command line application on your OS/2 box and
compare the log files (since they should be almost identical).
Hopefully, this gives a first hint where the problem is.
