so i did do another test i remove geany and cancel a folder inside .config , i reinstall it and With surprise i notice in the filetypes_extensions.conf exist just ring , i decomment some extention , i open a ring program and comment is ok because
i suppose the background is white , i add the colorscheme https://github.com/geany/geany-themes/ download zip and copy folder inside .config/geany ..., and when i choice a black do the same highlight comments but when use white
background i see good
but now the question is where is the problem ? o_O
