WDT timeout whne I use Canvas scroll()

[ziv2013]

I have written a simple test program:

1.Draw a Rectangle 2.Move it with scroll()

But the program would crash with below error

"E (27762) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (27762) task_wdt: - IDLE (CPU 0) E (27762) task_wdt: Tasks currently running: E (27762) task_wdt: CPU 0: E (27762) task_wdt: CPU 1: IDLE E (27762) task_wdt: Aborting.

`#include "fabgl.h"

const int WIDTH = 640; const int HEIGHT = 400;

// VGA 显示 fabgl::VGA16Controller DisplayController; Canvas cv(&DisplayController);

void setup() { Serial.begin(115200); DisplayController.begin(); // 设定分辨率 DisplayController.setResolution(VGA_640x400_60Hz);

//cv.setScrollingRegion(0, 0, WIDTH - 1, HEIGHT - 1);

cv.drawRectangle(10,100,90,200); }

int value = 0; boolean LeftToRight = true;

void loop() { if (value == WIDTH - 100) { LeftToRight = 1; } if (value == 0) { LeftToRight = 0; } if (LeftToRight == 0) { cv.scroll(1, 0); value++; } else { cv.scroll(-1, 0); value--; }

}`

And if I add delay(10) in the end of loop(), this issue would now occur. Is there any suggestion?
