Display ST7789 320*240 ripples when power is applied

I am sure that 99% of the problem is not related to the library.
The defect appears only when the display is turned on for the first time, incl. power supply.

Then everything works without ripples.
I tried to install a shunt capacitor to power the display, but there is no change.
The display is powered by 3.3 volts from the esp32 LDO regulator.
I feed the esp32 itself from USB.
I also tried to power it from the power bank - but nothing changes.
The distortion pattern itself is always the same - as if it was the ST7789 driver that controls it.
Upper half, left 9/10 parts horizontal dots, 1/10 part vertical dots.
Bottom half, left 9/10 parts horizontal stripes, 1/10 half - a few dots vertically.
Wrote in support of the manufacturer of the display driver - Sitronix Technology Corporation, but so far have not received a response.
I tried to play with the display drivers in the settings, but there is no effect either.
I tried to initialize the display with the command init(); and begin();
It would be desirable that when the device was turned on, the display would simply be black, and then display the image.
And here it turns out ripples, distortions - not a presentation of the device in general!
P.S.
As I thought - the problem of malnutrition.
Start sequences followed in the library

TFT_eSPI/TFT_Drivers/ST7789_Init.h

Line 136 in 1986bd2

delay(120);

It turns out that the LDO, which is installed on the esp32 board, does not allow maintaining a voltage level of 3.3 volts at the start of the microcontroller - esp32 sin with a large current at startup, which sometimes reaches 0.9 mA.
When the display was powered from a separate 3.3 volt power supply, the launch became without ripples and problems.
Quality nutrition is very important, especially in the era of modern microcontrollers.

You could

• Add a delay before initializing the display - this will circumvent the natually high boot current of the ESP32
• Add a capacitor to the 3v3 line, compensating for high boot current consumption
