We have built all the libraries from its source.( including DirectFB to freetype) We built freetype 2.3.9 and freetype 2.3.10 to check the issue. > 2) how did you update freetype? > a) by package manager (apt-get, yum, etc etc), updated unexpectedly > b) by package manager, manually specified > c) manually installation (e.g. ./configure && make && make install) > d) other We configure and build all the sources. ( c) manually installation (e.g. ./configure && make && make install)) Please find attached error.png [Broken ] and working.png [ Actual ].
