Would anybody who is experiencing SC_BAD_FLICKER not working please try
the following patch for /sys/i386/isa/videoio.c and see if it works?
Issues regarding what name for this option is most appropriate and
if this should be an option at all in the first place, will be
dealt with later. I would like to make things work first!
Thank you.
Kazu
