Problem with display memory corruption?

[tsr-exec]

Hi, I'm using your library with eastrising ssd1322 256x64x4 oled. It works fine except if I try to fill whole screen using drawPixel. Using clearDisplay in between drawing pixels will work, but I don't want to do this.

This code works:

void noise() {
  uint8_t  x, y;

  while (1) {

    for (x = 0; x < 256; x++) {
      for (y = 0; y < 64; y++) {
        display.drawPixel(x, y, random(15));
      }
      display.display();
       delay(10);
      display.clearDisplay();
    }
  }
}

---

This will result in corrupt display after about 200 pixels.

void noise() {
  uint8_t  x, y;

  while (1) {

    for (x = 0; x < 256; x++) {
      for (y = 0; y < 64; y++) {
        display.drawPixel(x, y, random(15));
      }
      display.display();
      delay(10);
    }
  }
}
