This doesn't sound promising. What would be the correct approach to solve this issue? And do you know why this is happening? Perhaps writing too fast, too many times or.... |

your program loop holded too long, RGB display cannot update in time |

Hi,
using the Arduino_GFX library I created a program that displays a real life ADC signal. What I noticed is that the complete display moves from right to left in small (random ?) steps. It's almost as if lines are drawn relatively with a small position error. However I'm definitely using absolute coordinates. And please note that the complete screen moves, including a small BMP picture.
The effect seems to get worse when using the touch capabilities of the screen.
Did anyone see this effect? And what to do?
Greetings.
