Status: RESOLVED WORKSFORME

If a table which extends past right window edge is scrolled left then extraneous
lines are drawn outside of the table mirroring the table border and cell dividers.
The scrolling has to be done slowly (not just a left/right jump scroll) to
produce this effect.
I have only seen this effect on the right edge of a table .. not on the left.
Redrawing the window (e.g. switching tabs) gets rid of the  extraneous lines.
I noticed this problem viewing the roadmap milestone releases table.
I don't know if this is an error in this table or an error in mozilla.


Reproducible: Always

Steps to Reproduce:
1. go to http://www.mozilla.org/roadmap.html
2. locate the table of milestone releases
3. make browser window narrow enough (800 px or less) so table extends off right
side of window, then click right arrow to scroll table into window
4. notice that the outside border and cell dividers are drawn to the right of
the table edge with a width of about 'a' in 'actual' to right edge of table
(about 2/3 of the width of the last cell) -- with a gap of width 'a' whitespace
between them.

It goes away if you minimize/change tabs/resize.

This bug is known in bugzilla-jp.
http://bugzilla.mozilla.gr.jp/show_bug.cgi?id=3497

but, bug 226637 block this bug.
a patch of attachment 136298 [details] [diff] [review] used build has no problem on Linux.
but this bug is still on Win32 build.

Here is testcase.
http://bugzilla.mozilla.gr.jp/attachment.cgi?id=1894&action=view

this problem only the table has "table-border: collapse;".
the case of "table-border: separate;" is here.

This bug is no problem on clicking scrollbar without thum and scroll allow.
But this problem reproduced when clicking scroll allow or draging thum.

I first observed this with Mozilla 1.6a, cannot reproduce with Mozilla 1.5 or older.

I no longer see this scrolling problem with the milestone table at the roadmap
URL (040117 trunk build).

I don't see it either anymore. I don't know if it's because the page changed or
something was fixed. Marking WFM.
