You are probably right, but in this case it doesn't help.
glBindTexture is never called before glTexParameter*() on the particle
texture, unless it is the only thing being rendered. Even calling
group.draw() before batch.draw() doesn't help.
FYI, I built a little workaround for this problem that doesn't require
me to sprinkle texture-reverting code thoughout my drawing code. I'm
subclassing SpriteTexturizer and calling set_state() twice, to ensure
that the glTexParameter() calls are made to the correct texture.
class SpriteTexturizer2(SpriteTexturizer):
def set_state(self):
SpriteTexturizer.set_state( self )
glPopAttrib()
SpriteTexturizer.set_state( self )
