Hi Abhimanyu,
I haven't used OpenCV, but I have a reasonable amount of experience writing image data to the frame buffer.
Are you using calls to ioctl and mmap to map the frame buffer into your application?
Are you setting the correct bit depth? By default in Bookworm, the frame buffer is 16 bits per pixel.
Can you post some code and a picture of what you are seeing on the raspberry pi? It would be much easier then to point you in the right direction.

Unfortunately, this description doesn't help me understand the problem you are seeing.... when i am using code in raspberry pi uneven color and pixels are visible.
