hello,
I'm trying to load textures in loop at an average of 1 fps. It
appears every iteration of the loop the image/texture data isn't
being
garbage collected and the script dies within a few minutes of a memory
error. Has anyone else encountered this leak? Is there
a better way to do this? It needs to be scalable so loading all the
images in at the start is not an option.
I've tried to explicitly reassign the self.img variable by setting it
to None and del self.img along with several other attempts. Any
ideas?
thanks, mark
