求问GUI界面黑边问题

Tokugawa

我自己移植的STemwin，在板子的液晶屏上初始画出的窗体总是有黑色区域，把建立窗体的程序拷贝到官方的文件里画出来就是正确的，没有黑边，拖动也正常，我感觉是我的某些配置出了问题，请教大神造成这种情况大概是因为什么？

正点原子

我感觉有可能是跟FreeRTOS的时序冲突了。。。有大神知道怎么回事吗

没代码你说个啥子

窗口创建任务：
void MainTask(void)
{
    GUI_Init();
    WM_SetDesktopColor(GUI_WHITE);      /* Automacally update desktop window */
    WM_SetCreateFlags(WM_CF_MEMDEV);  /* Use memory devices on all windows to avoid flicker */
    //PROGBAR_SetDefaultSkin(PROGBAR_SKIN_FLEX);
    //FRAMEWIN_SetDefaultSkin(FRAMEWIN_SKIN_FLEX);
    //PROGBAR_SetDefaultSkin(PROGBAR_SKIN_FLEX);
    //BUTTON_SetDefaultSkin(BUTTON_SKIN_FLEX);
    //CHECKBOX_SetDefaultSkin(CHECKBOX_SKIN_FLEX);
    //DROPDOWN_SetDefaultSkin(DROPDOWN_SKIN_FLEX);
    //SCROLLBAR_SetDefaultSkin(SCROLLBAR_SKIN_FLEX);
    //SLIDER_SetDefaultSkin(SLIDER_SKIN_FLEX);
    //HEADER_SetDefaultSkin(HEADER_SKIN_FLEX);
    //RADIO_SetDefaultSkin(RADIO_SKIN_FLEX);
        while(1)
        {
        GUI_ExecDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), &_cbCallback, 0, 0, 0);
        }
}
Emwin任务：
static void CONTROL_LCD(void const *argument){

        uint32_t PreviousWakeTime = osKernelSysTick();
        CALIBRATION_Check();
        GUI_SetBkColor(GUI_WHITE);
        GUI_SetColor(GUI_BLUE);
        GUI_Clear();
       for(;;){
              MainTask();

        }
}

主函数：
int main(void)
{
  /* Enable the CPU Cache */
  CPU_CACHE_Enable();

  /* STM32F7xx HAL library initialization:
       - Configure the Flash ART accelerator on ITCM interface
       - Configure the Systick to generate an interrupt each 1 msec
       - Set NVIC Group Priority to 4
       - Low Level Initialization
     */
  HAL_Init();  
  /* Configure the system clock to 200 Mhz */
  SystemClock_Config();
  
  /* Initialize LEDs */
  BSP_LED_Init(LED1);
          /* Initialize UART */
        Uart_init();
         /* Initialize LCD */
        LCD_Init();
        //CALIBRATION_Check();
  /* Thread 1 definition */
        osThreadDef(Communication,CONTROL_SIM8000, osPriorityNormal, 0,128);
        osThreadDef(LcdControl,CONTROL_LCD,   osPriorityNormal ,0,512);
        osThreadDef(Update,Update_TS,osPriorityNormal,0,128);
  /* Start thread 1 */
        CommunicationHandle = osThreadCreate(osThread(Communication), NULL);
   /* Start thread 2 */
        LCD_CONTROLHandle=osThreadCreate(osThread(LcdControl),NULL);
         /* Start thread 3 */
        UpdateHandle=osThreadCreate(osThread(Update),NULL);
  /* Start scheduler */
  osKernelStart();
  /* We should never get here as control is now taken by the scheduler */
  for(;;);
}

求大神指教
