OLED Display issue

[Looooopy]

I have tried to setup my OLED in QMK, but I only get a single line on the far right column am I missing some config?

I have tried:

• Two different OLED with same specs
• Have tried both SSD1306 and SH1106 if because I don't remembered what I bought for 5 years ago :)
  • SSD1306 => lot of scrambled dots
  • SH1106 => single column at the right side (think this is the model I have)

config.h

#define OLED_DISPLAY_128X64
#define OLED_IC OLED_IC_SH1106
#define OLED_TIMEOUT 15000

rules.mk

# MCU name
MCU = atmega32u4

# Bootloader selection
BOOTLOADER = caterina

# Build Options
#   change yes to no to disable
#
BOOTMAGIC_ENABLE = yes      # Enable Bootmagic Lite
MOUSEKEY_ENABLE = yes       # Mouse keys
EXTRAKEY_ENABLE = yes       # Audio control and System control
CONSOLE_ENABLE = no         # Console for debug
COMMAND_ENABLE = yes        # Commands for debug and configuration
NKRO_ENABLE = no            # Enable N-Key Rollover
BACKLIGHT_ENABLE = no       # Enable keyboard backlight functionality
RGBLIGHT_ENABLE = yes       # Enable keyboard RGB underglow
AUDIO_ENABLE = no           # Audio output
SPLIT_KEYBOARD = yes
UNICODEMAP_ENABLE = yes
OLED_ENABLE = yes
OLED_DRIVER = SSD1306
OLED_IC = SH1106

I forgot to add the function that actually writes to the OLED display

keymap.c

#ifdef OLED_ENABLE
uint16_t startup_timer;

static void render_logo(void) {
     static const char PROGMEM qmk_logo[] = {
         0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x86, 0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94,

     };

     oled_write_P(qmk_logo, false);
}

bool oled_task_user(void) {
    static bool finished_timer = false;
    if (!finished_timer && (timer_elapsed(startup_timer) < 1000)) {
        render_logo();
    } else {
        if (!finished_timer) {
            oled_clear();
            finished_timer = true;
        }
        // Host Keyboard Layer Status
        oled_write_P(PSTR("Layer: "), false);

        switch (get_highest_layer(layer_state)) {
            case _QWERTY:
                oled_write_P(PSTR("Default\n"), false);
                break;
            case _LOWER:

                break;
            default:
                // Or use the write_ln shortcut over adding '\n' to the end of your string
                oled_write_ln_P(PSTR("Undefined"), false);
        }
    }
    
    return false;
