Scrambled Text on SSD1306 Using ESP32-S2

Question

SSD1306 OLED display connected to an ESP32-S2 over hardware I2C. I noticed that the text will sometimes get scrambled or lag during a screen update. When left running long enough, the screen will get stuck and stop updating, despite serial monitor continuing to function. Does anyone know how to fix this? Here is a video of the laggy behavior: https://youtu.be/9OYW00cE24U

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
unsigned long drawState = 1;
unsigned long previousTime = 0;
unsigned long eventInterval = 4000;
#define OLED_ADDR 0x3C
#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 32
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);
void setup() {
  Serial.begin(115200);
  Wire.setClock(400000);
  if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
    Serial.println(F("SSD1306 allocation failed"));
    for (;;)
      ;
  }
}
int screenSwitchLast = millis();
void loop() {
if (millis() - screenSwitchLast >= eventInterval) {
    screenSwitchLast = millis();
switch (drawState) {
  case 1:
    drawTemp(); //draw Temperature
    break;
  case 2:
    drawHum(); //draw Humidity
    break;
}

drawState++;
if (drawState &gt; 2) {
  drawState = 1;
}

}
}
void drawTemp() {
  Serial.print("Temp ");
  Serial.println(millis());
  display.clearDisplay();
  display.setTextSize(2);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0, 12);
  display.print("Temp: ");
  display.print("10");
  display.print("F");
  display.display();
  delay(1);
}
void drawHum() {
  Serial.print("Hum ");
  Serial.println(millis());
  display.clearDisplay();
  display.setTextSize(2);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0, 12);
  display.print("Hum: ");
  display.print("20");
  display.print("%");
  display.display();
  delay(1);
}

I saw this post which recommends running screen update code on the second core but the ESP32-S2 only has 1 core. I'm at odds with how I'd get this to work reliably on a single core ESP32.
