in this case: self.cb = Callback(self.setup_gl_context) There are 3 instances of Callback in memory and they all reference a list that keeps growing whenever the scene is updated

	def setup_gl_context(self, *args):
	#clear_buffer
	glEnable(GL_DEPTH_TEST)
	self.fbo.clear_buffer()

blit_buffer problem

	def change_image(instance, photo, image_slider):
	"""open selected image, resize and blit into texture"""
	global currentTexture
	try:
	img = PILImage.open(instance.selection[0])
	except: pass
	img = img.resize((180,240), PILImage.BICUBIC)
	buf = img.tostring()
	with open('buffer.txt', 'w') as f:

this works on linux but not android.

	def change_image(instance, photo):
	"""open selected image, resize and blit into texture"""
	global currentTexture
	##try:
	img = PILImage.open(instance.selection[0])
	##print img
	currentTexture = Texture.create(size= (180,240))
	img2 = img.resize((180,240), PILImage.BICUBIC)
	buf = img2.tostring()
	currentTexture.blit_buffer(buf, colorfmt='rgb', bufferfmt='ubyte')

if i add the gridlayout directly to the scrollview instead of adding it to the relative layout the scroll works

	from kivy.uix.gridlayout import GridLayout
	from kivy.uix.anchorlayout import AnchorLayout
