abnormal temperature pattern, presence of stripes

[TramaLuca]

Good morning
I'm using the MLX90640ESF-BAB sensor (FOV 55x35) driven with an esp32 wroom32 programmed by the arduino IDE. The two resistors of 1kΩ and the two capacitors were inserted between the power supply, as indicated in the datasheet.
After calling the MLX90640CalculateTo() function I proceed to display the individual temperatures.
When viewing the temperature matrix you can see that the temperature is not uniform, but change in vertical bands with temperature difference over 10°.
How can I fix it?
I attach the documents for debugging.

Thanks for support.
