$Id: BUGS 228 2004-01-09 09:51:53Z sam $ Video rendering o ncurses' hashmap scrolling optimisation code causes the screen to occasionally flicker because it tries to optimise the vertical scrolling. With S-Lang, SLtt_Term_Cannot_Scroll prevents this unwanted behaviour. o some terminal emulators (Konsole, or the Linux VGA console) honour the blink attribute instead of using it for bold or bright like any other terminal emulator, hence reducing the amount of available colour pairs.
