pygame zero黑框

PYGAME ZERO SCREEN 显示不全, 有黑框, 請問各位知道解決方法嗎?

楼主能发代码看看吗

是這一串代码, 我用不同编辑器也一樣, 謝謝！

import pgzrun
import random
WIDTH = 1200
HEIGHT = 800
R = 100 # size of the circle
def draw():
screen.fill((255, 255, 255))
for x in range(R,WIDTH,2R):
for y in range(R,HEIGHT,2R):
for r in range(1,100,10):
screen.draw.filled_circle((x,y),R-r,
(random.randint(0,255),random.randint(0,255),random.randint(0,255)))
pgzrun.go()

update一下就可以
