Bullets misaligned vertically and horizontally on web page

• Component: Layout and Rendering
• Status: RESOLVED DUPLICATE

[David Kilzer (:ddkilzer)]

Summary:

The bullets in the first section of the page are misaligned (both horizontally and vertically) on various lines.

Steps to reproduce:

1. Open Safari/WebKit.
2. Note position of bullets in first section.

Expected results:

Bullets should align vertically, and they should align horizontally with the first line of text that they're associated with.

Actual results:

Bullets aren't aligned vertically or horizontally.

Regression:

This works with shipping Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).  Regression occurs with a locally-built debug build of WebKit r19202 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8N1037).

Notes:

None.

Okay, now I can't reproduce it with a locally-built debug build of WebKit r19207.

I doubt it was fixed within those revisions, though.  Might have been some kind of FOUC-related episode.

I saw this happen again, this time on CIA:

http://cia.navi.cx/stats/project/WebKit

Screenshot forthcoming.  I have no idea how to reproduce it yet.

Bullets drawn shifted down vertically on CIA.

More bullets shifted downward on CIA.  This is all the same page.

Still the same CIA page with shifted bullets.

I forgot a step in the original reproduction instructions.  I can't get this URL to reproduce on demand, though.

One more interesting tidbit: When this happens, scrolling vertically (in either direction) does NOT always redraw the bullets properly (is that "tearing?"), but scrolling horizontally (in either direction) will always redraw the bullets.

May have been fixed by r19441.

[John Sullivan]

There are two pages mentioned here:

http://www.worldsync.com:16080/syncdek/features.html

and

http://cia.navi.cx/stats/project/WebKit

The change for r19441 was about list editing rather than just list viewing, so it doesn't seem to be related. However, I can't reproduce a problem on either of these pages, and it sounds like most other people can't either. I'm going to move this to WORKSFORME; please reopen if anyone can still reproduce this.

Was not a regression per Bug 13157.
