stereo camera waiting for images

[nesquik011]

i am using windows , stereo camera 3840 X 1080 @ 60 i connect then down sample then split

    // Set the camera resolution to 3840x1080 (the combined stereo image)
    cap.set(cv::CAP_PROP_FRAME_WIDTH, 3840);
    cap.set(cv::CAP_PROP_FRAME_HEIGHT, 1080);
    cap.set(cv::CAP_PROP_FPS, 60);

            // Downsample the frame to 2560x720
        cv::resize(frame, frame_resized, cv::Size(2560, 720));

        // Split the downsampled frame into left and right images
        imLeft = frame_resized(cv::Rect(0, 0, 1280, 720)); // Left half
        imRight = frame_resized(cv::Rect(1280, 0, 1280, 720)); // Right half

and no matter what i do i still cant manage to fix this problem

i feeded rectified images and raw , still the same , by the way the everything works fine with orb slam2 so i guess nothing wrong with my calibration
