On OSX flycheck messages show up on the monitor where the mouse cursor is

[carloscheddar]

Using OSX flycheck popup messages for errors and warnings show up on the monitor that has the mouse cursor instead of only displaying on top of the spacemacs window.

@carloscheddar I've failed to reproduce this issue, using a regular homebrew build of Emacs 25.1. No matter where my mouse cursor is, the tooltip always appears right below the point (i.e. the Emacs cursor).

Would you tell me your Emacs version and your OS X version?

[carloscheddar]

I'm running OS X El Capitan and a port of Emacs 24.5.1 https://github.com/railwaycat/homebrew-emacsmacport
Also just to be clear this happens when I run it in a GUI.

@carloscheddar Could you show me the value of pos-tip-use-relative-coordinates in your Emacs?

[swsnr]

@carloscheddar Being unable to reproduce the issue I'm fishing in muddy waters; I have pushed a change which explicitly passes the coordinates of the frame to pos-tip, based on an uneducated guess of what could probably cause this issue 😊

I'd appreciate if you could test the next MELPA build of this extension to see whether the problem disappears. I can't promise anything, though ☺️

Were you able to test the fix?

[carloscheddar]

I updated all packages today and tested the fix but it's still happening. Let me know if I can provide any more information about this.

@carloscheddar Could you try to reproduce the issue in normal GNU Emacs?

[aaronjensen]

I can reproduce this if I use a window manager like slate to move the window. It doesn't happen every time, but occasionally the tooltip will appear in the wrong place after a movement.

edit: every time i switch back to the emacs window from another window the tooltip is in the wrong place. If I resize the window or move it, the next tooltip will appear positioned correctly.

I'm using regular gnu emacs on osx (24.5.1)

After being bothered by this for a long time, I forked this package and tried to fix it myself. Despite being able to consistently reproduce this, I can't figure out a fix. I hate recommending other packages on issues, but switching to flycheck-popup-tip works perfectly out of the box on MacOS for me, and claims to work better in TUI as well.

It looks like this is the route taken by Doom as well: doomemacs/doomemacs#318
