Hi Rabbi, As Jason points out if your are doing the write image from the main loop and the view is multi-threaded then the main loop will be running in a parallel with the rendering.
The way to do it properly is to use a final draw callback to capture the image and then write it to the disk, or if you don't want to do the write in the draw thread for performance reasons pass the completed image to a thread safe queue that is read by a separate database writing threading.
