The reason, and how to workaround it, is maybe what's explained in freetype 2.8's changelog: https://sourceforge.net/projects/freetype/files/freetype2/2.8/ ================ II. IMPORTANT BUG FIXES - `Light' auto-hinting mode no longer uses TrueType metrics for TrueType fonts. This bug was introduced in version 2.4.6, causing horizontal scaling also. Almost all GNU/Linux distributions (with Fedora as a notable exception) disabled the corresponding patch for good reasons; chances are thus high that you won't notice a difference. If optical backward compatibility for legacy applications is necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option. However, it is strongly recommended to avoid that, adjusting font sizes instead. - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType now scales the font linearly again (bug introduced in version 2.4.6). ================ In short: recompile your freetype 2.8/2.9 with this patch applied: ================ --- include/freetype/config/ftoption.h-orig 2018-04-22 11:41:36.038775440 +0200 +++ include/freetype/config/ftoption.h 2018-05-11 11:55:03.185874240 +0200 @@ -909,7 +909,7 @@ /* */ /* This problematic commit is now reverted (more or less). */ /* */ -/* #define AF_CONFIG_OPTION_TT_SIZE_METRICS */ +#define AF_CONFIG_OPTION_TT_SIZE_METRICS /* */ ================ I had to install freetype 2.9 on my CentOS7 and noticed the font height change. Applied the patch, now it looks like w/ freetype 2.7. Regards, -- wwp
