i don't see any difference...

it's a couple pages of forms, the rectangles and separator lines appear to be
present but the text is missing except for a few lone characters here and
there.

of course that could be unrelated to the NaN problem...

there are some more traces about unimplemented methods:
0104:fixme:d2d:d2d_path_geometry_ComputeArea iface 37DC4E90, transform
01EEB644, tolerance 2.50000000e-01, area 01EEB640 stub!
0104:fixme:d2d:d2d_geometry_sink_SetSegmentFlags iface 37E22A60, flags 0 stub!
0104:fixme:d2d:d2d_device_context_DrawGeometry Ignoring stroke style 37DEC698.

will attach a copy-pasted test that reproduces the NaN loop...
