I'm not sure about FF < 3.6 - I can't test other versions this moment.
Here is example code:

<html xmlns="http://www.w3.org/1999/xhtml">

<title> Замыленные инпуты в FF 3.6 / Fuzzy (smudged, blurred) inputs in FF 3.6 </title>

<style type="text/css">
div, td { opacity: .9; }
.txt { height: 14px; }
</style>
</head>
<body>
<div>

<table>
<tr>
<td><input type="checkbox" class="chk" /></td>

</tr>
<tr>

Ria, can you maybe post a screenshot of what you're seeing? I don't see an obvious problem on the testcase, but I'm on Mac.... This might be Windows-only (and then not a layout bug).

The reporter has already posted a screenshot in the URL field and I see the same with the latest trunk build, it seems even uglier here. Tested on Vista.

It looks OK in 3.5.7 on Ubuntu. Ugly on 3.7a2pre (Gecko 20100215) Windows XP Pro.

It also looks ugly on 3.0.19pre and 3.5.9pre (both being private builds with libpng-1.4.1, but that should not be relevant), on WinXP Pro. So this seems to be a very old regression, somewhere between FF-2.0 and FF-3.0.19pre.

roc, is this a Windows native theming issue, or something in layout-land?
I'm not sure actually...
Regression range:
works - no textboxes though:

Looks like the "b=using opacity with windows native widgets causes bogus rendering/lack of rendering; r=stuart" (no bug number listed) checkin vlad made there.
This is distinctly looking like a windows native theme + cairo issue to me.

(In reply to comment #8)
I forgot. I was tracking the check boxes and not the text boxes. Do you need a range for when the text boxes disappeared too? Its quite a bit earlier.

Presumably that was part of early cairo work or something....
