Sorry for digging this old post....but... I have the same Issue. My application should update the display "as smooth as possible" that means the short flickering for a full refresh is ok (takes less than 1 second) but not the whole startup flickering-clearing-UIFlowLogo-flickering-nothinguntilmydatagetready-flickering thing. My solution is now a wait instead of sleep which draws the battery too fast. Any idea how to do that in UIFlow?
