This is one of the videos which showed the after effects of the coloured screen issue.
Have been using this driver for a few days now and no coloured screen hangs.
However the 100% GPU load still happens occasionally. This problem does not really impact any of my PC apps so not a big deal.
I would recommend using the uninstallation of the previous driver before you insatll the new driver. AMD provide a tool for this function.
