<![CDATA[drawJpg refresh rate is slow]]>

#define SPI_FREQUENCY 80000000 

1. M5.Lcd.drawJpg(f1, sizeof(f1));

2. M5GFX display.drawJpg(f1, sizeof(f1), 0, 0);

I'm rendering a const unsigned char f1[] image on the LCD, but the refresh rate is slow. You can see a black area at the bottom when updating drawJpg.

I'm using the M5Stack Core2. Any help would be greatly appreciated!

Thank you!
