I’ve got a consistent repro on my config with this patch. If I start
emacs then open a dired buffer in a dir that has images in it, then
hit return on one of the images, the current line goes blank while the
image loads. If I kill the buffer and reopen the same one it does not
repro.

I cannot reproduce this in emacs -Q as it’s much faster than whatever
my config is doing whenever I open an image.

That said, I haven’t seen any line flickers yet aside from that. I’ll
keep trying it out and report back.
