as Dmitry pointed out - you can almost eliminate these effects by:
a. Disable Display power Management completely. Do this as Administrator AND User.
b. Completely disable kpowersaved

Disabling a just as user didn't stop these effects to happen. Since I also disabled it as Administrator - I barely had a black screen anymore !
