posframe blink when working with lsp-mode in emac-mac-port

[P233]

I record a screencast for this issue. The posframe blinks frequently when candidates come from lsp-mode, but in other major modes it doesn't bink at all.

This is happened on the latest emacs mac port (arm64 version), I am not sure if it is also happened in other emacs versions. If you need any other information, please let me know.

Thanks for the hard working of posframe!

Thanks for the quick reply.

Not a big deal. I am now using numbers shortcut instead of up or down keys, that won't cause posframe blink.

I post this issue because I thought you might have some ideas. But if you think this is a randam case, or maybe not compatible with some specific version of emacs mac port. I'll close this issue.

I switch to TabNine completion instead of the lsp completion this moning, the blink issue just gone. Probably caused by the lsp mode.

I don't use LSP but I get the same issue when using company-capf in an emacs-lisp buffer on a Mac.

@Yevgnen I have updated posframe to solve flicker in windows, can you try the master posframe code in macos? maybe useful in macos too :-)

@tumashu Hi, unfortunately the current version e104c0d0ee8db4a5fc852b3fc951e52989ee8755 does not seem work on my macOS 12.1 and GNU Emacs 27.2 (build 1, x86_64-apple-darwin21.1.0, Carbon Version 165 AppKit 2113) of 2021-11-01. Every two or three C-p or C-n cause the flickers.
