hi,
It's all dependant on your OS, video card and driver?
So which driver?
eg, with ubuntu there is this link which mentions it:

I tried this again with this in the main loop:
for i in xrange(1000):
screen.fill( (0,0,0) )
t=(pygame.time.get_ticks()*240)//1000
for r in rectangles:
screen.fill( (255,0,0), r.move(-t,-t) )
realscreen.blit(screen,(0,0))
pygame.display.flip()
It is indeed a fair bit s

You might try losing the clock.tick_busy_loop(60), I found on MacOS X
that I would get tearing frequently if I throttled the framerate
arbitrarily, might help on X-win too. Since this is just busy-waiting
anyway it might even use less cpu without it, regardless it shouldn't
use more.

I'm trying to do full-screen scrolling, using pygame in X-Windows. As
far as I can tell, there's no way around the problem of tearing. Is
that true? Here's a simple example that gives me problems:
import pygame
from pygame.locals import *
from random import randint
pygame.init()
opts = pygame.FUL
