User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9b5pre) Gecko/2008032104 Minefield/3.0b5pre
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9b5pre) Gecko/2008032104 Minefield/3.0b5pre

This happens on 64bit Linux. Whenever I click any checkbox on a page, no matter if it is checked or not, it disappears (screenshot included). If I use tab, and focus changes to another checkbox, the one that looses focus appears again, and the next one disappears. If I click anywhere on the page making the checkbox focused loose the focus, it appears.


Reproducible: Always

Steps to Reproduce:
1. Click on any checkbox on the webpage
Actual Results:  
Clicked checkbox disappeared


I used this build: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/firefox-3.0b5pre.en-US.linux-x86_64.tar.bz2 and it has a problem.
It was present in previous few betas as well, but those I compiled myself, and I wasn't sure if it was not because wrong compilation options.
I use Archlinux, gtk-2.12.9, cairo-1.4.14 (but I guess Firefox3 uses its own version)

I confirm the same problem on linux, with the betas 3,4  and 5 of firefox, but with a 32bit version.

I use gtk-2.12.1-2 and gtk-qt-engine-0.8.3

I'm having the same problem on my two Ubuntu Hardy Desktops (32 Bit). It happens with all Firefox betas I have tried until now.

I have gtk-2.12.9 and gtk-qt-engine 0.8.
It seems the problem is related to 'Qt' theme selected for gtk-qt-engine.
When, in 'GTK styles and fonts' section of KDE Control Center, I select either 'use my KDE Style in GTK applications' (for KDE I use Plastik), or 'Use another style' and select 'Qt', this bug occurs.
When I change the 'another style' to somethign else - the bug is gone. I now use 'Clearlooks' style and it's ok.
I also tried Gimp, and it doesn't have this problem, no matter which style I use.

I can confirm seeing this with Kubuntu 8.04 (32 bit) and Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008051202 Firefox/3.0.  

I can also confirm that the fix/workaround of System Settings -> Appearance -> GTK Styles and Fonts -> (*) Use another style: Clearlooks has fixed the issue for me.

Confirm this with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008052904 Minefield/3.0pre and gtk-qt-engine_0.8-2 (Debian "lenny").

This bug is both Firefox and gtk-qt-engine.
Firefox just uses gtk_paint_focus() is a way that gtk-qt-engine doesn't expect.
gtk-qt-engine has following code:
=== cut ===
        QColor bg(qApp->palette().active().background());
        painter.fillRect(0,0,w,h,bg);
        qApp->style().drawPrimitive(QStyle::PE_FocusRect, &painter, QRect(0,0,w,h), qApp->palette().active(), QStyle::Style_Default, QStyleOption(bg));
=== cut ===
This draws focus rect on the pixmap filled of bgcolor, and then this pixmap is drawn without any transparency ontop of checkmark using GDK gdk_draw_drawable().

I'm currently investigating how to make it honor transparency.

Just fixed gtk-qt-engine. Will send patch to both gtk-qt-author and Debian maintainer.
