What's your terminal? Urxvt per chance? See, e.g. https://bbs.archlinux.org/viewtopic.php?id=84600 (Although I'm not sure it is good advice to put "term rxvt-256color" in the screenrc. There's "term screen-256color" after all. For me, "URxvt*termName: rxvt-unicode-256color", "term screen-256color" has worked perfectly for quite some time.)
