Hi ,
I work with Arduino IDE 2.3.2

#include "Arduino_H7_Video.h"
#include "ArduinoGraphics.h"

Arduino_H7_Video Display(800, 480, GigaDisplayShield);
//Arduino_H7_Video Display(1024, 768, USBCVideo);

void setup() {
  Display.begin();
  
  Display.beginDraw();
  Display.background(255, 255, 255);
  Display.clear();
  Display.fill(0x008184);
  Display.circle(Display.width()/2, Display.height()/2, 300);
  Display.stroke(255, 255, 255);
  Display.noFill();
  for (int i=0; i<30; i++) {
    Display.circle((Display.width()/2)-55+5, Display.height()/2, 110-i);
    Display.circle((Display.width()/2)+55-5, Display.height()/2, 110-i);
  }
  Display.fill(255, 255, 255);
  Display.rect((Display.width()/2)-55-16+5, (Display.height()/2)-5, 32, 10);
  Display.fill(255, 255, 255);
  Display.rect((Display.width()/2)+55-16-5, (Display.height()/2)-5, 32, 10);
  Display.fill(255, 255, 255);
  Display.rect((Display.width()/2)+55-5-5, (Display.height()/2)-16, 10, 32);
  Display.endDraw();
}

void loop() { }

I adding this library Arduino_USBHostMbed5.h and the Display work correctly

  Display.rect((Display.width()/2)+55-5-5, (Display.height()/2)-16, 10, 32);
  Display.endDraw();
}

void loop() { }

WHY?

Another Question , why if I load this scketch whit Platoformio Arduino giga R1 it Crashing?

Hi @holly197,
Did you test all the Arduino_H7_Video examples?
Did you face this issue in all sketches?

What's the version of Mbed OS Giga Boards package?

Mbed OS is 4.1.1

I try to load not all examples , but different examples whit same result
GigaDisplay_GFX display Basic
ArduinoGigaDisplay Geometrical-shape
lvgl bar_lvgl

For what it is worth the first sketch runs fine on mine. Shows the logo

I am running on recent nightly build (0403) - no changes in IDE since then...
Giga board 4.1.1
