I do have a message (with 2 images and multiple PDF attachments) where it looks like this: 15095 97% - notmuch-show-command-hook 15095 97% - redisplay 16 0% - redisplay_internal (C function) 16 0%- eval 16 0% spaceline-ml-main when global-hl-line-mode is on. Unfortunately, I cannot share this message. Generally, it only happens when one of the attached images is visible in the window. If I stumble across this problem with a message that I can share, I'll post it here. signature.asc Description: PGP signature ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

I made a test message with 10 copies of a (black and white) 3k x 3k jpeg image, enabled global-hl-line-mode, but I don't notice any navigation problems. I wonder if there could be an interaction with some other package? Or do I need bigger / more images? d ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

I've tracked it down: it happens when multiple large images are attached to the email (and displayed inline) and global-hl-line-mode is turned on. The former slows down redisplay, the latter makes redisplay do something with every cursor movement. ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

Hard to debug without a sample message, or a more definite pattern. Do you notice a threshold in terms of numbers of attachements? I can imagine there is some bad behaviour involving large numbers of buttons when running redisplay. d ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org
