we have a problem with ncurses.
we use ncurses for handle menu and text.
for draw a nice background we write directly to /dev/fb0.
this is the normal output: https://docs.google.com/file/d/0B0RH...NrQXlSS2s/edit
after a random hits of UP/DOWN buttons, 3 black lines appear under the "Press [h] for help".
this is the corrupted output: https://docs.google.com/file/d/0B0RH...it?usp=sharing
background images are different but the bug should be clear.
here you can find the ncurses menu handler: https://github.com/tux-mind/tf201-de...r/nGUI2.c#L432
thanks for the help.
