Reproducible: Always Steps to Reproduce: Set background-color: rgba( 255, 255, 255, 0.4 ) for the container div and all it's children. Actual Results: First child of the container will have no background at all. Expected Results: All child elements of the container must have background, as it's set in the css. As is shown on the example page, bug disappears if there is some visible text in the container before children with the background-color property, or there is some visible text before the container.
Would you mind posting a screenshot of what that testcase looks like for you? As far as I can tell the rendering I'm seeing on that test page is correct...
Created attachment 536010 [details] Bug testcase screenshot All the words "test" are wrapped in spans's with background-color: rgba(255, 255, 255, 0.4); As you can see on the screenshot, the first word on the first row doesn't have any background.
WFM on 4.0.1 & Trunk on WinXP.
Yeah, I don't see the issue in that screenshot in either my trunk Linux build or the 4.0.1 binary I just downloaded from mozilla. Dmitry, are you using a distro build or one of the mozilla ones?
I'm using the package from the official ubuntu repositories - 4.0.1+build1+nobinonly-0ubuntu0.11.04.3 I don't see the issue in Firefox 4.0.1 for windows
Can you try a mozilla.org Linux build, please?
I still see the bug in the mozilla.org build. How I tried: 1)Downloaded tar.bz archive from mozilla org 2)Extracted archive contents 3)Entered the program folder and then run program with ./firefox I don't know if it interferes with distro package.
Did you quit the distro Firefox first?
Yes, I did. Also I've checked if there is any running firefox process
OK. What Xorg version is this? This is starting to sound like a bug in the interaction of cairo and your X server...

My system has 7.6+4ubuntu3.1 package installed.
(In reply to comment #11) > My system has 7.6+4ubuntu3.1 package installed. Is this related to the version of Xorg that Dmitry is using?
I think that's xorg-server 1.7.6, which is fairly old now, but it's probably more likely related to device-dependant drivers or maybe even pixman. Strange though that it would be specific to first-child of first-child. I don't know what we'd be doing different in that particular case. I can't rule out a problem on our-side, but I can't reproduce.
I've updated firefox to the latest version 5 and the bug is still there.
I can actually confirm this issue on Mozilla/5.0 (Ubuntu; X11; Linux x86_64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1 Strangly this only happens when the parent and child rgba values are the same... if they differ it doesnt happen. I cannot reproduce on Fx3.6.12 WinXP or Fx9.0.1 Win7 See attached screenshot + testcase
im using the latest Ubuntu 11.10 (64bit) with gnome-panel

Sjoerd and Dmitry, can you describe the video drivers that X is using, please? Look for "Video Driver" in /var/log/Xorg.0.log. e.g. [ 22.307] (II) Module radeon: vendor="X.Org Foundation" [ 22.307] compiled for 1.11.2, module version = 6.14.3 [ 22.307] Module class: X.Org Video Driver [ 22.307] ABI class: X.Org Video Driver, version 11.0
[ 8.026] (II) intel: Driver for Intel Integrated Graphics Chipsets: i810, [ 8.028] ABI class: X.Org Video Driver, version 10.0 Its a Sandy Bridge (Core i7 2630QM) laptop with integrated graphics Video playback / Animations / Gnome Shell / Scrolling is generally smooth, no real performance issues in day-to-day programming :)
I use Lenovo t420 with integrated graphics now and can still reproduce the error. I had another laptop in the time when the bug was reported, but it also had intel graphics.

Thanks. Looks like it could be worth filing a bug at freedesktop for the Intel driver. (I can't reproduce with radeon, nor with Xvnc, which I assume uses the sw framebuffer and pixman.)
