Hi Killian,

Well, I haven't looked at the code in xfstt for a very, very long time
now, but there may be differences in the way the actual pixel size is
computed from the screen resolution + point size. rounding differences
come to mind..

If the resolutions are different, you'll get different pixel sizes.
Actually, the computation is simply something along the lines of:

  pixel_size = point_size * 72 / resolution

Do you mean that gfontsel runs on Windows ? Or do you compare
gfontsel with "xfstt" and "xfsft" ??

Best regards,
