Selecting menu items, the menu display appears unsteady as there appears to be a 1 pixel layout error that's immediately corrected by a screen redraw
Reproducible: Always
Steps to Reproduce:
1. Select several menu items from the menu at left one after another
2. Observe boundary of menu, and menu items, for movement
Actual Results:
Page objects in menu are unsteady as they reposition themselves slightly when the pages load
Expected Results:
Menu appears steady - Firefox 1.07 and previous handles this ok.

Windows only? I've checked this bug using Firefox 1.5 RC1 on a Mac, and that seems OK
Regressed in the last month or so? I've checked it against a Firefox beta 1 build from 06/09/2005 on Windows XP, and this behaviour isn't present in that build.
Not just me? I can reproduce it on a different machine running Windows XP and again Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8) Gecko/20051025 Firefox/1.5 and a CRT monitor. (The machine from which I reported the bug has a flat screen).

Reduced test case at:
http://it-help.bathspa.ac.uk/testcase_315519.html
css for left-hand menu is this:
div.nav { position: fixed; }
div.nav ul { padding-left: 0em; }
div.nav li { display: block; }
html is this:
<body>
<div class="nav">
<ul>
<li><a href="testcase_315519.html" class="current"> Home Page</a></li>
</ul>
</div>
<p style="margin-left: 9em">Select menu item at left. The item ideally shouldn't twitch horizontally ...</p>
</body>
</html>

I have a hard time seeing the bug with the testcase, but I think this is WFM in my debug build that has the "frame display lists" patch in it (bug 317375).
Please test again when that bug becomes fixed.
Depends on: 317375

This should be fixed now that bug 317375 is fixed.
Mark, please test with the latest nightly trunk build that has the patch in?

The testcase is not very useful IMO.
No response from the reporter to questions.
I am marking this fixed since there is no flicker when using Firefox 1.5.0.2 rv: 1.8.0.2 build 20060410 or a recent 1.8 branch nightly.
For trunk builds, there is still bug 324819.
> 1. Select several menu items from the menu at left one after another
> 2. Observe boundary of menu, and menu items, for movement
This looks more to be one of the outline bugs; see bug 261196.
