Subject: 27.2; Displaying many images take all memory
Date: Thu, 11 Nov 2021 09:00:31 +0000

Hello,

I see you changed image-dired to use image-mode in emacs-29 instead of using like
before image-magick.  That's fine I used the same approach two years ago
in Helm, but switched back quickly to image-dired because it was taking
all memory and it was not recoverable until I kill emacs. I thought it
was my fault but I see new image-dired in emacs-29 have same problem:

1) emacs -Q
2) Open a large image directory with dired
3) Open files one by one with C-t i until memory is full (use f3 C-t i
C-n f4 etc...). Memory starts to grow seriously after around 70 files
for me.

Killing the image-dired buffer changes nothing, I have to restart emacs
to recover memory.

And now unfortunately I have no more alternatives with Helm in emacs-29 since
image-dired uses inconditionally this.

You can reproduce the same bug with helm by setting
helm-ff-display-image-native to `t` and from helm-find-files hit
C-<down> repetitively in same image directory (not using
helm-ff-display-image-native i.e. with nil value is now broken with new image-dired).
