I have ili9488 display without touch, esp32-s3. Screen powered by 5V, signal lines via 3.3V. The image is displayed well, the colors are also well reproduced. However, after a second there are jumps, colors diverge, the content jumps, the image is illegible, stops. You can see it in the foto.
Connection diagram for ESP.
Cs-10; dc-7; rst-4; LED-13; mosi-11; sclk-12; with miso connected and as without, no improvement.
Program written on esphome, I want to use it for Home Assistant.
The most interesting thing is that when I hold the mass of the system with my finger, the screen works and no other errors pop up on logs.
