I am so far unable to find a recipe without including org-mode in the mix.  An org-mode recipe is quite simple:

  1. Create a new org-mode file.
  2. M-x org-indent-mode
  3. M-x visual-line-mode
  4. Insert text below, replacing the image name with a large image of your choosing (wider than the standard frame width), placed in the same directory as your org file
  5. M-x org-display-inline-images
  6. Move point down towards the image
  7. Emacs hangs

I’m sorry to report that this fix seems to have introduced a hard lockup in org-display-inline-images,
when displaying images in an org file with larger images.  

I just confirmed by reverting to the state just before your patch was applied to master.  It may have
something to do with the final large image fix.

Please provide a recipe to reproduce these lockups.

Thanks.
