The display is really flickering. If you want my code, let me know. Thanks for response

Try to use i2c driver from greiman instead of slow buggy Wire.
I mean run this example https://github.com/greiman/SSD1306Ascii/blob/master/examples/AvrI2c128x64/AvrI2c128x64.ino.
Also, call the method to increase i2c frequency to 400 000 instead of default slow one.

My guess is that you have a clear display call in your main loop. This will cause flickering.

You're clearing the display each time through your loop. Remember that there is no buffer with this library.

-Edit-

You're not even using this library in your code? You're using an Adafruit one.

Looks like you clear the screen each time you enter loop so it will flicker.

Clearing the screen requires writing 1024 bytes of zero to the display memory.

oled,clear() takes about 46 ms.

Run this code in loop. It flickers.

void loop() {
  uint32_t m = micros();
  oled.clear();
  oled.print("\nmicros: ");
  oled.print(micros() - m);
  }
