visual glitch when used with native line numbers in emacs master

[CSRaghunandan]

I recently compiled emacs master build which contains the native line numbers implemented by Eli Zaretski. I gave it a shot and found a visual glitch with page-break-lines-mode. Please refer to the screenshot below:

Thanks. I guess that window-width still reports the full window width with this mode, whereas with linum-mode is just reports the usable width. Should be something I can patch, but before I investigate that might I suggest you ask on the list whether this difference is expected?

Maybe you can use line-number-display-width which will return the width of the line number window and subtract it with window-width - 1 ?

Maybe. I don't currently have a HEAD version of Emacs available, and don't have time to dig into this just yet, so if you want to propose a change that works for you and will still work with older Emacs versions, I'd be happy to integrate it.

I do not use line numbers myself and presently, I do not have the time to contribute a patch. Maybe someone else more capable will fix the issue :) I'm a noob with elisp

@CSRaghunandan It might be best to file a bug report about this. You don't have to provide a patch. Just list the steps starting with emacs -Q..

1. Start emacs -Q.
2. Clone this repo: https://github.com/purcell/page-break-lines
3. Load this package, enable line numbers, etc. to get to the visual bug you are seeing. and also reference this thread in that bug report.
