I am relatively new in python and started coding in pygame. For some reason, when I am rendering some images on a surface, it doesn't blit the images. But when I minimize it and then open it again, it works fine. Is there any fix to this problem? Thanks in adavance.

My code, just in case if something's wrong in it:

import pygame

displayWidth = 1920
displayHeight = 1080

pygame.init()

gameDisplay = pygame.display.set_mode((displayWidth,displayHeight),pygame.FULLSCREEN)
pygame.display.set_caption('Road Fighters')
clock = pygame.time.Clock()

car = pygame.image.load('Car.png')
grassLeft = pygame.image.load('Grass Left.png')
grassRight = pygame.image.load('Grass Right.png')
blank = pygame.image.load('Left.png')
lining = pygame.image.load('Lining.png')
miniMap = pygame.image.load('Progress.png')
miniCar = pygame.image.load('Small Car.png')
road = pygame.image.load('Road.png')

def car(x,y):
    gameDisplay.blit(car, (x,y))

def draw():
    gameDisplay.blit(blank,(0,0))
    gameDisplay.blit(miniMap,(670,0))
    gameDisplay.blit(grassLeft,(720,0))
    gameDisplay.blit(lining,(1020,0))
    gameDisplay.blit(road,(1030,0))
    gameDisplay.blit(lining,(1610,0))
    gameDisplay.blit(grassRight,(1620,0))

def gameloop():
    while True:
        for event in pygame.event.get():
##            if event.type == 2 or event.type == 12:
##                pygame.quit()
##                quit()
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT: dx = -3
                elif event.key == pygame.K_RIGHT: dx = 3
            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT: dx += 3
                elif event.key == pygame.K_RIGHT: dx += -3
draw()
gameloop()

You need to add a pygame.display.flip() to your game loop.
