Hi again!
Although I've managed to remove the tearing artifacts in our dga program, the
rendering speed (fps) is slow. I'm planning to use page flipping in our code
but the program hangs when we run it. This is a part of our code that do the
page flipping:

Thanks for your help guys! I've managed to remove the tearing on our DGA
program but the consequence is that the rendering speed went from a max of 15
fps (w/o vsync) to 9 fps (w/ vsync). Initially, the image reading from the
camera and the copying to the framebuffer was in a single thread (w/c

We didn't use OpenGL or implemented page flipping because we don't want to make
big modifications on the code in such a very short time.

Hi guys! We're developing a DGA program that render full screen at 1280x1024 16
bpp 15fps the video image read from a sony camera, but we're experiencing
tearing artifacts during rendering. This is a part of the code that copies the
data to the frame buffer:
