ESP8266 Overlap mode with touch screen

[sfxsfl]

Hi,

first of all. Thank you for the great piece of work and the effort you spend developing it.
I'm using the ESP8266 with an ili9341 with Touch in SPI Overlap mode.

In my simple sketch I'm using drawString within the setup and getTouch in loop. As a result
I'm getting artifacts on the screen at the last character.

`
#include <TFT_eSPI.h>
TFT_eSPI tft = TFT_eSPI(); // Invoke library

void setup(void) {
tft.init();
tft.setRotation(1);
tft.fillScreen(TFT_DARKGREY);
tft.setTextColor(TFT_WHITE,TFT_BLACK); tft.setTextSize(1);
// We can now plot text on screen using the "drawString"
tft.drawString("Welcome the ESP8266", 100, 110, 2);
}

void loop() {
uint16_t x,y;
#if 1
if (tft.getTouch(&x, &y)) {
delay(100);
}
#endif
delay(200);
}

#define TFT_SPI_ OVERLAP

//#define LOAD_FONT8N // Font 8. Alternative to Font 8 above, slightly narrower, so 3 digits fit a 160 pixel TFT
#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

// Comment out the #define below to stop the SPIFFS filing system and smooth font code being loaded
// this will save ~20kbytes of FLASH
#define SMOOTH_FONT

#define SPI_FREQUENCY 27000000
// The XPT2046 requires a lower SPI clock rate of 2.5MHz so we define that here:
#define SPI_TOUCH_FREQUENCY 2500000
// #define SPI_TOUCH_FREQUENCY 1000000

Thanks in advance
