Taken from this answer, I get following completely filled and unscrollable horizontal scrollbar:

enter image description here

I guess it might be due to following css-rule:

.comment-body {
    max-width: 630px;
    overflow: auto;
    overflow-y: hidden;

Because when I manually add overflow-x: hidden; with the chrome dev-console, the scrollbar vanishes.

Additionally when I actually scroll the scrollbar the following happens (color inversion extension disabled):


For reference, I am using Chrome Version 37.0.2062.124 m on Windows 7 with a monitor res of 1680x1050

  • Same browser, same OS, no repro. Why is it dark? Good chance whatever theme you got that makes it dark, also breaks some CSS. Try disabling the theme and see. Commented Oct 1, 2014 at 12:02
  • @ShadowWizard disabled the extension, repro remains. Commented Oct 1, 2014 at 12:03
  • So some kind of dark magic... hopefully others would be able to repro as well. Commented Oct 1, 2014 at 12:05
  • It looks like you're using SOUP, which, as of v1.22, injects the CSS rule you quoted to work around another bug. I'll try to fix it if I can reproduce it. If you find more new bugs, it may be a good idea to check if disabling SOUP fixes them, and, if so, report them directly on the SOUP page rather than here. In any case, thanks for the report!

  • (Alas, I can't reproduce this on my Chromium 37.0.2062.120 / Ubuntu 14.04 (281580), with or without SOUP. I don't have a convenient Windows box at hand to check there; for all I know, it might be font-dependent or something weird like that.) Commented Oct 5, 2014 at 21:33

    (Just tossed a status-deferred on there so the SE devs know this isn't their bug.)

  • @Laura Replacing that with status-norepro since, well, it's not our bug. :)

I was able to "kill" the bug by disabling SOUP, for now I dropped a comment at the SOUP Page on stackapps

As of now, this is officially acknowledged as a bug in the list of known bugs. Additionally Ilmari has already incorporated a fix into the development branch ;)

  • I'm still not able to reproduce this. :( Anyway, since it's apparently reproducible for you, would you mind testing a few things for me? 1) What is the actual width of the div.comment-body element, and of the span.comment-copy inside it, as shown when you hover the mouse over the tags in the "Elements" tab in developer tools? 2) Does changing the CSS max-width to 629px or 631px in developer tools change anything? 3) What about adding width: 630px to the CSS? Thanks! Commented Oct 6, 2014 at 14:17
  • 1) div.comment-body: 620px, span.comment-copy: 621px. 2) neither changes anything 3) div.comment-body now has 630px width, no more scrollbar. span.comment-copy now has 624px width; Commented Oct 6, 2014 at 14:23
  • Huh, that's... interesting. What about setting width: 620px, or both that and max-width: 620px? Commented Oct 6, 2014 at 14:46
  • @IlmariKaronen no effect. neither with setting width only nor with setting both.... Commented Oct 6, 2014 at 14:48
  • Hmm, what about adding padding-right: 2px? Commented Oct 6, 2014 at 15:01
  • @IlmariKaronen that works a charm. div.comment-body is now 620px wide and span.comment-copy 606px. Scrollbar is not there anymore. Thanks for reminding my why I don't like css ;) Commented Oct 6, 2014 at 15:06

    Honestly, I think this is a Chrome bug; there's no good reason why the span.comment-copy should ever be wider than the div.comment.body element, as long as it doesn't exceed the maximum width. Anyway, I've added the padding-right kluge to the SOUP devel branch, and it'll be included in the SOUP v1.24 release (which I plan on making sometime this week). Commented Oct 6, 2014 at 15:28
