It's not related to VIM. I get it very often while using Midnight Command in gnome-terminal and viewing (F3 key) text files. Running MC in other terminals like xterm or konsole does not have such issues. I even tried gnome-terminal in a different window manager (FVWM) to rule out the Gnome desktop. gnome-terminal still cause that garbage. Ctrl-L is a quick work-around to get rid of that garage.
