Suggest send a mail in emacs-devel.

@aaronjensen maybe this is a good temp solution :-), I will disable lower-frame in macos

Switch anothet WM, and try again, maybe gnome problem

I have tested lucid, frame show and hide or frame move seem to very slow.

@dgutov Today, I test lucid again, and find the slow may posn-at-point ``` (benchmark 1000 '(posn-at-point (point))) ``` "Elapsed time: 0.684959s" this let posframe slow when first show posframe ```...

@dgutov I use pyim (an input method) to test posframe, and find that posn-at-point let posframe ~half second lag

I don't understand too, maybe posn-at-point let emacs lock half second? or posn-at-point+input let emacs lock?

It is not frame creation's problem,

When I replace posframe's posn-at-point to a variable test, then I setq test a proper value, lucid have no lags. so I think it is posn-at-point's problem, but posn-at-point's speed...

@dgutov Info has been added, thanks very very very much for your and Martin Rudalics hard word, if no your long disscuss and coding, this problem can not be resolved.
