I guess a driver issue, see
But maybe theres another problem:
(Testing your script + data on win xp sp3, ati catalyst drivers 12.4)
with pyglet 1.1.4release I see a correct rendering
with pyglet 1.2dev (updated now, utc 13:00) I got a bad rendering: black screen except for the entire NE quadrant which looks green.
The stock cocos samples test_tiles.py and test_tmx.py show also the same behavior.
I will investigate this problem, probably tomorrow.
Could you tell me which pyglet are you using in windows ?
Can you try to run the pyglet sample noisy.py ? It gives a black screen here.
(noisy.py can be found in the pyglet tarball / checkout under examples/noisy )
