The doc string assumes "normal" operation, it doesn't assume some Lisp command runs for a long time, thus preventing redisplay. > Also, I repeated my tests manually calling image-clear-cache every Nth > image. Every invocation of image-clear-cache does reduce the memory > consumption, but there is always some residual remaining unrealeased > (see the attached images). The residual seems to scale with the number > of images in the cache before clearing. I think that's a simple result of how clear-image-cache is implemented, I suggest to read the code.
