Electrical – Horizontal offset with generic SSD1306 OLED display

I bought a generic OLED 128×64 display on ebay and had some success in getting it running with the Adafruit SSD1306 library.
I ported the initialization function to C and am driving the LCD using the SPI interface. However, when the splash screen appears, there is a horizontal offset.

I think should be possible to patch this by modifying the display function. However, my question is, is there a cleaner way to do this in the configuration settings for the OLED display. The relevant initialization settings that I am using are given below:

void ssd1306_init(uint8_t vccstate) {

    // Init sequence
    ssd1306_command(SSD1306_DISPLAYOFF);                    // 0xAE
    ssd1306_command(SSD1306_SETDISPLAYCLOCKDIV);            // 0xD5
    ssd1306_command(0x80);                                  // the suggested ratio 0x80

    ssd1306_command(SSD1306_SETMULTIPLEX);                  // 0xA8
    ssd1306_command(SSD1306_LCDHEIGHT - 1);

    ssd1306_command(SSD1306_SETDISPLAYOFFSET);              // 0xD3
    ssd1306_command(0x0);                                   // just changes the horizontal offset
    ssd1306_command(SSD1306_SETSTARTLINE | 0x0);            // line #0
    ssd1306_command(SSD1306_CHARGEPUMP);                    // 0x8D
    if (vccstate == SSD1306_EXTERNALVCC)
    {
        ssd1306_command(0x10);
    }
    else
    {
        ssd1306_command(0x14);
    }
    ssd1306_command(SSD1306_MEMORYMODE);                    // 0x20
    ssd1306_command(0x00);                                  // 0x0 act like ks0108
    ssd1306_command(SSD1306_SEGREMAP | 0x1);
    ssd1306_command(SSD1306_COMSCANDEC);

    if( SSD1306_LCDWIDTH == 128 && SSD1306_LCDHEIGHT == 32) {
        ssd1306_command(SSD1306_SETCOMPINS);                    // 0xDA
        ssd1306_command(0x02);
        ssd1306_command(SSD1306_SETCONTRAST);                   // 0x81
        ssd1306_command(0x8F);
    }
    else if (SSD1306_LCDWIDTH == 128 && SSD1306_LCDHEIGHT == 64) {
        ssd1306_command(SSD1306_SETCOMPINS);                    // 0xDA
        ssd1306_command(0x12);
        ssd1306_command(SSD1306_SETCONTRAST);                   // 0x81
