I have a patch that loads two new images every frame with two pix_image]--[pix_texture]. Only the latest two images are needed for each frame. I'm also using pix_image "thread 0" so that the images are loaded before the current frame is displayed, and pix_texture "rectangle 0, quality 2".
After some time Pd is using all my memory (I have 8GB ram and no swap) and the system becomes unresponsive.
Using valgrind I see there is a severe leak, probably in Magick loader (log attached). Same problem whether I use png or tif.
