Hi,
You need to enable double buffering. Without this, you will be trying to write to the buffer and trying to display it on the screen at the same time. This leads to the fluttering effect that you speak of.
With double buffering, you will write to the back buffer while displaying the front buffer. Once the write is complete, you do a swap (quick operation) which removes the fluttering.
