It took couple of seconds to bring up all the stuff on screen, but it didn't flicker otherwise. I can't tell if double buffering is working or not, but it does not have any ugly flickering at least. Update rate for information seems to be once per every 2,5 seconds (approx) and screen draws without any aftifacts between refreshes.

I didn't have to swipe away. I also tested multiple restarts to see whether the results vary. Looks good to me.
