Almost, leave the SSM line uncommented, thats the one that turns it off.
To avoid misunderstanding: Is the following correct? ``` /*#ifdef GDK_WINDOWING_QUARTZ*/ /*# if ! GTK_CHECK_VERSION(3,16,0)*/ /* "retina" (HiDPI) display support on OS X - requires disabling buffered draw * on older GTK versions */ SSM(sci, SCI_SETBUFFEREDDRAW, 0, 0); /*# endif*/ /*#endif*/ ```
