Popup alignment in php-mode inexplicably broken for me.

[aaronbieber]

I'm having the strangest problem all of a sudden with alignment of popup menus in auto-complete when using php-mode. This is what it looks like:

To try to diagnose whether this was just an issue with my config, I tried:

1. Rolling back my .emacs by several weeks (it's in git, of course).
2. Deleting my entire ~/.emacs.d/elpa directory and re-downloading/re-compiling all packages.

Neither of these helped. This problem doesn't seem to affect text-mode or lisp-interaction-mode, though, as shown here:

I've also opened an issue with php-mode, but they haven't been able to reproduce it. I have attempted to debug what is going on in popup.el, but admittedly my Lisp isn't very strong and I can't figure out how the placement of the left edge of the popup is computed.

Any help or direction on how to figure this out would be greatly appreciated.

I discovered that this behavior only happens when fci-mode is turned on, which leads me to believe that it is directly related to that package, and probably not a popup.el issue.

I am going to leave this open for now until someone from this project takes a peek at it and maybe helps to confirm this for me.

@aaronbieber, looks like posn-at-point problem. To verify this you can try popup-el version previous to this commit.

I have the same problem with the python-mode. I'm not using any proportional font so it's not related to some other bug reports.
I'm using el-get and I tried with different version of this mode, and I found that if I checkout tag v0.5.2 I don't have this problem but with v0.5.3 I do have it, so it must be a regression between those 2 releases

After some more investigation I found that this is the commit that caused the problem:

Could you show us minimum configuration for reproducing this issue ?

[diasjorge]

@syohex I found this minimum configuration. https://gist.github.com/diasjorge/4b6217ec577ce4c1b1f7
It appears to be an interaction between fci-mode and popup-el. It actually breaks in all modes I tested but I only had fci-mode activated with python-mode. I also found this bug which appears similar company-mode/company-mode#180

I really don't understand the code you made to deal with transparent overlays or something like that to say more but seems related.

I see there's this bug open for a long time alpaker/fill-column-indicator#21

I am having this issue as well... anyone has a good solution? This is a popup for a English -> Chinese dictionary.

Did you eventually solve it? @aaronbieber

[syohex]

I suppose your issue is different from this, because it looks you use non monospaced font. It is difficult to support such fonts.

[yilihong]

Actually I do use mono spaced font. The English is "Hack", Chinese is also mono spaced. Don't know what's going on there...
