I already broken my head over this problem.
Strange vertical stripes appeared on the display.
Explain, please, did I broken something in the settings, or is it a sign of the imminent demise of the display?

ESP32-S2 device, ILI9488 display, VScode + PlatformIO environment, Windows 10 system. Environment components are the freshest.

I just don't remember when (under which version of lvgl_esp32_drivers or framework esp-idf) there were no artifacts, there was a big break in working with the project.
I can't roll back, I would have known that there would be such a problem - I would have made a commit.
