ST7701S 16bit RGB wrong colors and gost pictures

[SkydiveH]

I use a 2.1" round display with the ESP32-S3. I face the problem, that the colors are wrong ( changing the Endian does not correct it) and that the picture is flickering. I run the PDQGraficTest. It works with wrong colors and the display is stable, but when I change the orientation, there are gost pictures ( Orientation 2)

If I use a MaTouch 2.1" Displayunit, the colors are correct, all is stable. My Init code is

#include <Wire.h>
#include <Arduino_GFX_Library.h>

#define TFT_BL 38
#define AV_GRN 0x06A2 // Aviation Green -> Blue Arc
#define AV_RED 0xE804 // Aviation Red -> Warning
#define AV_BLU 0x18DC // Aviation Blue ->
#define AV_YEL 0xE742 // Aviation Yellow -> Yellow Arc
#define AV_MGN 0xE8BC // Aviation Magenta ->
#define AV_AMB 0xFD26 // Aviation Amber -> Caution
#define AV_WHT 0xFFFF // Aviation White -> White Arc
#define AV_BLK 0x0000 // Aviation Black
// Color Definitions
#define LGRY 0x0F7D // Light Grey

void setup()

digitalWrite(TFT_BL,LOW);

gfx->begin();
gfx->fillScreen(AV_RED);
gfx->fillRect(100,100,100,20,AV_BLU);
delay(2000);

gfx->fillScreen(AV_AMB);

}
void loop()

Hope somebody can help me here.
