Hi! I have installed the latest version of the library https://github.com/moononournation/Arduino_GFX I also adapted the display initialization file according to my own https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-5 Here is the file

define ESP32_4827S043

#if defined(ESP32_4827S043)
#define GFX_DEV_DEVICE ESP32_4827S043
#define GFX_BL 2
#define RGB_PANEL

// Uncomment for ST7262 IPS LCD 1024x600
 Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
     5 /* DE */, 3 /* VSYNC */, 46 /* HSYNC */, 7 /* PCLK */,

I'm trying the touch button test. Here's a Sketch:

It's working! The sensor is responding. The image is being displayed!

But when you click on any area of the screen, interference appears on the display. As I understand it, this happens at the moment of updating the screen! Is it possible to adjust something further to avoid pixel displacement?
