I suppose theres also a tilemap somewhere, being that you use
tiles.RectMapCollider ?

Ok, I think the simplest scenario fulfilling your description is
Scene
ScrollManager
RectMapLayer showing the tiles, obtained with
tiles.load('map_fname')
ScrollableLayer
JetSprite
JetSteam
I modified the stock test_tiles.py which has all except the particles adding
a JetSteam to the car, thats test_tiles_1.py.
It worked as expected here, meaning no strange images.
Tested with all combinations of (cocos 0.4.0, cocos trunk r1080) x (pyglet
1.1.4 , pyglet 1.2dev branch default rev 8d20445ae6e2
Just in case I modified further by making SpriteCar mimic the details you
exposed about JetSprite, that was test_tiles_2.py
As before, all worked as expected, no artifacts.
I suggest you try the two scripts.
Do they show the defect ?
If not, there should be some difference between the scripts and your code.
pastebins:
test_tiles_1.py -> http://pastebin.com/1rZP3HLJ
test_tiles_2.py -> http://pastebin.com/FPgqqry9
to run them put into the same directory you have the stock test_tiles.py ,
this way the scripts will find the necessary resources.
