Setting text color on LCD prevents breaks text output

[LukeSkaff]

If you set the display text color then when you output text to the display in the same cursor location the display code does not clear the previous written text when overwriting the text. See below sample code an pictures.

#include "Arduino.h"
#include <M5Unified.h>

int counter1 = 0;
int counter2 = 209;

void setup() {
  auto cfg = M5.config();
  M5.begin(cfg);
  delay(500);
  M5.Display.clear();
  delay(100);
}

void loop() {
  M5.update();

  M5.Display.setTextColor(TFT_GREEN); //--COMMENT OUT THIS LINE AND IT WILL WORK--

  M5.Display.setCursor(0, 20);
  M5.Display.print( "C1: ");
  M5.Display.print( counter1);

  M5.Display.setCursor(0, 30);
  M5.Display.print( "C2: ");
  M5.Display.print( counter2);

  counter1++;
  counter2++;
  delay(100);
}

Without color set

With color set

it was of course me doing something stupid, you have to set the background color, below fixed it M5.Display.setTextColor(TFT_GREEN, TFT_BLACK);
