Status: REOPENED

(Core :: Layout, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b2) Gecko/20050521

Looking at any web page that has table content wider than the current
browser window causes a horizontal scroll bar to appear at the bottom
of the window. The end of the scroll bar should display triangles that
point right and left. This version of Mozilla does not show the triangles;
they previously did appear correctly. Also, in the space near where the
triangles should appear, there may be a lot of garbage vertical lines where
the scroll bar should be.

Reproducible: Always

Steps to Reproduce:
1. go to www.netscape.com
2. resize the browser window to be narrower than the Netscape page
3.

Actual Results:  
The scroll bar appears at the bottom of the screen, but the triangles
are missing. Also, there are extra lines in the scroll bar space
near where the triangles should be.

Expected Results:  
The triangles should appear, and there should be no extra vertical lines
in the space near where the triangles should be, it should be filled
with a solid dark gray color as seen in the vertical scroll bar.

This only occurs in the Modern theme. The "garbage" between the scrollbar and
the corners looks like some repainting issue - it might already been filed,
since i think it's been there for a while. Hmm, atm I can't figure out what
changes have caused this... Nothing in the theme files looks suspicious, must be
something else.

Both horizontal and vertical scrollbars are OK for me (using both modern and
classic on a new profile).  So probably Mac only.

OK, guessing Core: Layout.

The repainting issue seems to be new as well.

Could bug 240276 have caused this? Guessing that the arrow not showing is
obscured by bug 292312 until that was fixed, the issue doesn't seem to be there
in 2005042710.

probably not me...

roc, it seems that the repainting issue was caused by your checkin in bug 240276
(2005-04-28 14:57). The repainting issue is there in a build I made from a
checkout with -D "2004-04-28 1500 PDT". Backing out the patch in bug 240276
makes it go way. The arrows are there as well, but the cause of missing arrows
needs some more investigation.

Hmm, It looks like the arrows disappeared at the same time... Here's my
observations:

No arrows in a build from 2005-04-28 23:30 PDT with the patch from bug 292312
(changes in layout/generic/nsGfxScrollFrame.cpp) applied.

That would make a regression range (for the arrows disappearing) of:

No arrows if I back out the checkins made 2005-04-28 16:47-48 and 15:03-15:17

KaiRo, not really a 1.0a blocker, but perhaps a 1.0b blocker?

Did any changes happen to location of the arrow images on mac or something like
that?

Actually, we need to look into it, but I don't think a minor look (not feel)
problem in modern (which is not the default theme) blocks a developer-testing
release such as Alpha. Beta perhaps, yes. Please try to investigate and remind
us for beta.

I haven't seen this for a very long time now. So, it looks like wfm. Anyway, it would be nice if some other mac user can confirm that the issue is gone.

Karsten, can you confirm this (wfm)?

[Robert Kaiser]

ugh. sorry.

Wanted to mark this at a different bug.


Is this bug still seen, or has it been fixed on trunk already?
