Line number showing double on soft wrap

[BlackWolf]

Sometimes when having long lines and using soft wrap, the line number is repeated instead of showing a dot (this happens with line 26 in the first screenshot). The line numbers are correct (so the line displayed as 26 is line 26 and 27 starts where it should) and the content shows fine. Also, the markup seems fine as far as I can tell (see second screenshot).

The issue might be related to #2429

@BlackWolf Do you have the React editor enabled in Atom > Preferences > Settings?

[BlackWolf]

No, I don't, but this indeed fixes the issue! I can't find any information about what exactly the react editor is/does. Should it have been enabled by default?

No, I don't, but this indeed fixes the issue!

That's interesting - thanks for following up! Does this consistently happen for very long lines for you? If you can reliably reproduce the problem -- could you provide the steps to reproduce it?

I can't find any information about what exactly the react editor is/does.

It's a rewrite of the editor component. It's already in Atom, but it's opt-in until while we 🔨 at the rough edges.

Should it have been enabled by default?

No, it shouldn't. But it will be on by default soon (hopefully).

It seems to occur when having a file with long lines that can be scrolled - in some way, it is definitely related to scrolling, as it only occurs for lines that are outside of the current view and then scrolled into view, but I can't pinpoint the exact cause. When having such a file the issue can be reproduced by scrolling, though.

Kind of a "minimum" working example for me:

(be sure to have the size of the atom window set in a way that the file needs to be scrolled to view the last view lines)

Thanks so much for that example, @BlackWolf -- that reproduces the issue for me as well!

Since this will be fixed with the React editor, I'll keep this open and just add fixes #2443 text to the pull request that makes the React editor default. 💡 /cc @nathansobo -- I'm guessing fixing this in the current editor is not worth the effort.
