Performance issues about which-key-posframe HOT 2 OPEN

which-key--hide-popup - why would it try to hide the popup when it was never opened, I'm just moving cursor around?

1. I think this is because the fowlling code in which-key:

(add-hook 'pre-command-hook #'which-key--hide-popup)

2. Maybe you can use profiler to see which functions cause the lag, and please post the profiler report here in order to let us investigate the possible issues.

I'm seeing this too. It's strange because I've used this package for a long time now, and only in the past few weeks has this become an issue for me. A few notes:

I don't see this issue on my Mac, which is running v28/master, from this project.

On GNU/Linux I'm using the v28/master + pgtk fork from the AUR. I think pgtk might be part of the problem. @agzam, are you using pgtk perchance? I'm not sure if it's a thing on Mac.

When I open something (e.g., a big .org file), moving the cursor around initially is slow; I'd disable which-key-posframe and, voila - it gets fast again. I would re-enable the mode - and it is still fast, it won't go back to lagging as when I open the file. So, it is slow only when the first time I open the file.

I observe this too, but it usually becomes slow again once I do something to actually activate which-key-posframe (eg <C-x>, pause...).

I can reproduce this with a very minimal setup: emacs -Q and then:

(require 'which-key)
(require 'which-key-posframe)

(which-key-mode 1)
(which-key-posframe-mode 1)

...so I think we can rule out interactions with other packages.

Maybe you can use profiler to see which functions cause the lag, and please post the profiler report here in order to let us investigate the possible issues.
