Black display when using setcursor() even when changing fontsizes from 1 to 7

[linxcow]

Describe the bug

Using following code after installing m5stickcplus 0.1.0 i get always black display. I also note in my other projects that using setCursor(0, 0, x) to change font or size values between 1 and 7 some dont show any display at all , why is that?

      `
      void loop() {
          tftSprite.fillSprite(BLACK);   // Fill the canvas with black.                         
          tftSprite.setCursor(0, 0, 1);  // Set the cursor position and use the 1-point font.
          tftSprite.printf("AXP Temp: %.1fC \r\n",
                           M5.Axp.GetTempInAXP192());  // Get the temperature of AXP192.
                           
          tftSprite.printf("Bat: %.3fv %.1fma\r\n",
                           M5.Axp.GetBatVoltage(),
                           M5.Axp.GetBatCurrent());  // Output voltage and current of // Bat.
                                                     
          tftSprite.printf("Usb: %.2fv %.1fma\r\n",
                           M5.Axp.GetVBusVoltage(),
                           M5.Axp.GetVBusCurrent());  // Output current and voltage of USB
                                                      
          tftSprite.printf("5V-In: %.2fv %.1fma\r\n",
            M5.Axp.GetVinVoltage(), M5.Axp.GetVinCurrent());
          tftSprite.printf("Bat power %.1fmw", M5.Axp.GetBatPower());
          tftSprite.pushSprite(2, 2);   // Where to place our sprite ( 2 pixel marge for best display )
      
          // 0x01 long press(1s), 0x02 press
          // No display or flashing with next line ???
          // if (M5.Axp.GetBtnPress() == 0x02)  { esp_restart(); }  // Restart when powerbutton is pressed shortly
      
          if (M5.BtnA.wasPressed()) {  // When Main button pressed powerdown LCD & Backlight 
            M5.Axp.SetLDO2(false);
          } 
          else if (M5.BtnB.wasPressed()) { // When bottom button pressed powerup LCD & Backlight 
            M5.Axp.SetLDO2(true);
          }
          M5.update();  // Detect whether the keystroke state has changed.
          delay(100);
      }`

After a lot of testing I found the the screenbreath() required values have changed nothing is mentioned in the online help Most of the online help is not uptodate and incomplete. So my code was working but too dim to see

Setting tftSprite.setCursor(0, 0, x);
font 3 does not display anything also undocumented.

Are you using the latest library? I don't reproduce your problem at all, and switching fonts works fine!
