Noob question: FT_LOAD_COMPUTE_METRICS (lv_freetype_glyph.c) not working on Windows?

Hi,

On Windows, lv_freetype_glyph.c (line 160):

error = FT_Load_Glyph(face, glyph_index, FT_LOAD_COMPUTE_METRICS | FT_LOAD_NO_AUTOHINT);

Sets the rows of the glyph to 0 whereas on Linux I get the correct number.
Do I miss a Freetype configuration or something (using version 2.13.3 on Windows and using version 2.12.1 on Linux) ? I can get the correct number of rows by passing FT_LOAD_RENDER but that does not seem to be a good fix. Anyone knows why this happens?

cheers,
Gabor
