One of the primary differences in freetype-2.8 and prior Ubuntu versions of freetype is the introduction of TT_CONFIG_OPTION_SUBPIXEL_HINTING in /include/freetype/config/ftoption.h in freetype-2.7.X and later. The default value is:
#define TT_CONFIG_OPTION_SUBPIXEL_HINTING 2 This needs to be undefined (uncommented) in order for freetype-2.7 and 2.8 to render fonts identically to prior versions of Ubuntu freetype (freetype-2.6.X and earlier). The diff file (freetype_2.8-0.2ubuntu2.diff.gz) at https://launchpad.net/ubuntu/+source/freetype/2.8-0.2ubuntu2 enables FT_CONFIG_OPTION_SUBPIXEL_RENDERING in /include/freetype/config/ftoption.h with: #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING This properly enables subpixel rendering to render fonts identical to MS cleartype, however, if TT_CONFIG_OPTION_SUBPIXEL_HINTING is also set then the fonts are rendered differently than before. So, this problem is fixed simply by undefining TT_CONFIG_OPTION_SUBPIXEL_HINTING. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722508 Title: Font hinting appears broken on 17.10 beta To manage notifications about this bug go to: https://bugs.launchpad.net/qt/+bug/1722508/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
