      Description

      Please, look at this code.
      It does almost nothing, just refreshing black screen 60 times per sec.
      But it takes more than 50% of modern processor core (and with above average GPU)

      Now, change canvas dimension from 1801x1801 to 1800x1800
      Performance will improve significantly (2-3 times better).
