求助：裸机+stemwin怎么不能画竖线？中英文字符显示正常

遗忘的城市

MiniSTM32 V3.3 裸机程序+STemWin 5.28, 2.0寸 ILI9225G 176*220液晶屏，显示方向：横屏（220*176）。
用LCD驱动直接画线，画矩形，位图，都正常。
但是emwin不能画圆，不能画矩形，也不能画竖线，画出来只显示成水平线，显示BMP位图也是乱的，呈撕裂模样看不清。但是显示中英文字符是正常的，画水平线也是正常的。
请问这是怎么回事？
GUI驱动只添加了打点函数：
static void LcdWriteReg(U16 Data) {
  // ... TBD by user
  LCD_WR_REG(Data);
}

static void LcdWriteData(U16 Data) {
  // ... TBD by user
  LCD_WR_DATAX(Data);
}

static void LcdWriteDataMultiple(U16 * pData, int NumItems) {
  while (NumItems--) {
    // ... TBD by user
LCD_WR_DATAX(*pData++);
  }
}

static void LcdReadDataMultiple(U16 * pData, int NumItems) {
  while (NumItems--) {
    // ... TBD by user
*pData++ = LCD_RD_DATA();
  }
}
void LCD_X_Config(void) {
  GUI_DEVICE * pDevice;
  CONFIG_FLEXCOLOR Config = {0};
  GUI_PORT_API PortAPI = {0};
  //
  // Set display driver and color conversion
  //
  pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_565, 0, 0);
  //
  // Display driver configuration, required for Lin-driver
  //
  LCD_SetSizeEx (0, XSIZE_PHYS , YSIZE_PHYS);
  LCD_SetVSizeEx(0, VXSIZE_PHYS, VYSIZE_PHYS);
  //
  // Orientation
  //
  Config.Orientation = GUI_SWAP_XY;// | GUI_MIRROR_Y;
  GUIDRV_FlexColor_Config(pDevice, &Config);
  //
  // Set controller and operation mode
  //
  PortAPI.pfWrite16_A0  = LcdWriteReg;
  PortAPI.pfWrite16_A1  = LcdWriteData;
  PortAPI.pfWriteM16_A1 = LcdWriteDataMultiple;
  PortAPI.pfReadM16_A1  = LcdReadDataMultiple;
  GUIDRV_FlexColor_SetFunc(pDevice, &PortAPI, GUIDRV_FLEXCOLOR_F66708, GUIDRV_FLEXCOLOR_M16C0B16);
}

int LCD_X_DisplayDriver(unsigned LayerIndex, unsigned Cmd, void * pData) {
  int r;
  (void) LayerIndex;
  (void) pData;
  
  switch (Cmd) {
  case LCD_X_INITCONTROLLER: {
    //
    // Called during the initialization process in order to set up the
    // display controller and put it into operation. If the display
    // controller is not initialized by any external routine this needs
    // to be adapted by the customer...
    //
    // ...
   
LCD_Init();
    return 0;
  }
  default:
    r = -1;
  }
  return r;
}
