On Ubuntu 20.04, I use the latest self compiled git master version as
shown below:
$ git log -1
commit 5d8608ea744727b9a74874cfe8aca4656a4a9fea (HEAD -> master,
origin/master, origin/HEAD)
Author: Hongyi Zhao <hongyi.zhao@gmail.com>
Date: Sat Jun 19 12:02:51 2021 +0800
new file: .emacs.d/init.company-wordfreq.el
new file: .emacs.d/init.lsp-latex
new file: .emacs.d/init.straight.el
I noticed the following strange problem:
First start Emacs like this:
$ /usr/local/bin/emacs -Q
Then run `M-x list-input-methods` and scroll down the screen in input
method panel using the mouse or arrow key will cause Emacs
unresponsive for about 1 minute.
See the attached file for the screenshot that was captured when this
problem occurred.
Regards

It isn't necessarily strange: Emacs looks for the fonts needed to display the relevant characters, so if you have a lot of fonts installed, and some character is not supported, it will take Emacs a lot of time to scan all those fonts. ^ permalink raw reply [flat|nested] 17+ messages in thread

In "emacs -Q" or without the -Q switch? If the former, what are the differences between the two Emacs configurations, the slow one and the fast one? If the latter, then the reason for the faster operation is in the init files that you get with the "apt" distribution. ^ permalink raw reply [flat|nested] 17+ messages in thread

That explains at least part of the slowness. The fast version also doesn't include any text-shaping engine, which might speed up Emacs, but prevents it from correctly displaying complex scripts. What are the Emacs versions of the two builds? ^ permalink raw reply [flat|nested] 17+ messages in thread

Sorry, I see now that its Emacs 26.3 and 28. And I guess the Emacs 28 build also used the default optimization options, unlike what I said before. So the only difference I see is the text-shaping engine that is missing in the "fast" version. I don't think I understand why that should have such a profound effect on the speed of finding fonts, sorry. ^ permalink raw reply [flat|nested] 17+ messages in thread
