win32api and python causing my screen to go black when it moves the mouse

For whatever reason the screen is going black after the second or third movement of the mouse. First is the function i use to move the mouse:

import ctypes
import time

SendInput = ctypes.windll.user32.SendInput


def MoveMouse(x, y):
    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    x = int(x*(65536/ctypes.windll.user32.GetSystemMetrics(0))+1)
    y = int(y*(65536/ctypes.windll.user32.GetSystemMetrics(1))+1)
    ii_.mi = MouseInput(x, y, 0, 0x0001 | 0x8000, 1, ctypes.pointer(extra))
    x = Input(ctypes.c_ulong(0), ii_)
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

this causes the screen to go black

import numpy as np
from PIL import ImageGrab
import cv2
import time
import win32api, win32con
from directkeys import PressKey,ReleaseKey, W, A, S, D, MoveMouse
from grabscreen import grab_screen
x_pad = 0
y_pad = 0
def left():
    PressKey(W)
    PressKey(A)
    #ReleaseKey(W)
    ReleaseKey(D)
    #ReleaseKey(A)
    time.sleep(.9)
    ReleaseKey(A)
def leftClick():
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0)
    time.sleep(.1)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
    print ("Click.")
def mousePos(cord):
    win32api.SetCursorPos((x_pad + cord[0], y_pad + cord[1]))
def screen_record(): 
    last_time = time.time()
    while(True):
        # 800x600 windowed mode for GTA 5, at the top left position of your main screen.
        # 40 px accounts for title bar. 
        printscreen =  grab_screen(region=(0,40,800,640))
        #rgb_im = printscreen.convert('RGB')
        pixels =int(printscreen[300, 300, 0]) 
        print(pixels)
        #r, g, b = printscreen.getpixel((551, 350 ))
        if pixels == 255:
            #if r == 127and g == 26 and b == 25:
            x, y = win32api.GetCursorPos()
            #x += 44
            time.sleep(1)
            MoveMouse(x, y)
            time.sleep(1)
#


        #print (r, g, b)
screen_record()

Thanks any help would be appreciated. To summarize i need help determining why the Move Mouse function is causing my entire desktop monitor to black out until the function is no longer being used.

Had the same issue, try changing in:

ii_.mi = MouseInput(x, y, 0, 0x0001 | 0x8000, 1, ctypes.pointer(extra))

the fifth parameter (I.E. "1") to a 0, so it looks like this:

ii_.mi = MouseInput(x, y, 0, 0x0001 | 0x8000, 0, ctypes.pointer(extra))

Worked for me... Good luck
