White tabs and toolbars in Firefox beta

[mavit.org.uk]

I'm seeing rendering glitches in Firefox 4 beta versions. The navigation toolbar and tabs appear with a white background. This sounds minor, but it makes it difficult to tell which tab is selected:



The problem disappears if I edit xorg.conf and disable the RENDER extension. It also disappears if I run Firefox 4 beta under VNC:



I don't see this problem on my Intel-based laptop, only on my NVidia-based desktop, which makes me think this may be a problem with the NVidia hardware or drivers.

I'm running Fedora 13 with the following:

OpenGL renderer string: GeForce GT 240/PCI/SSE2
OpenGL version string: 3.3.0 NVIDIA 260.19.29

I'm using the Firefox 4 beta packages from
http://repos.fedorapeople.org/repos/spot/firefox4/, and the NVidia drivers from RPM Fusion:

> rpm -qa \*nvidia\* | sort
akmod-nvidia-260.19.29-1.fc13.i686
kmod-nvidia-2.6.33.5-124.fc13.i686.PAE-260.19.29-1.fc13.i686
kmod-nvidia-2.6.34.7-66.fc13.i686.PAE-260.19.29-1.fc13.1.i686
nvidia-settings-1.0-9.fc13.i686
nvidia-xconfig-1.0-6.fc13.i686
xorg-x11-drv-nvidia-260.19.29-2.fc13.i686

Try disabling GFX acceleration.

I'm not sure what you mean by this.

If you mean that I should set "RenderAccel" to "off", then that makes no difference.

However, if you mean I should switch to the Nouveau driver, that does indeed fix the problem.

What's your cairo version? (run `rpm -q cairo` to find out)

If it's not `cairo-1.10.2-1.fc14` then you must upgrade it.

You can disregard my previous post - I think it's not relevant.

He's running Fedora 13 (stated in his post quite clearly). He will not be affected by the cairo bug, which was with gradients and not Firefox.

OP: I'm not seeing what you see, but I am on Fedora 14 (using spot's FF4b8 RPMs).

Firefox doesn't use GTK and gradients?

Firefox4 presumably has a bundled copy of cairo-1.10 without the workaround added.

Indeed, this is the case.

For anyone else with the same issue, it's discussed in more detail at http://www.nvnews.net/vbulletin/showthread.php?t=157352 and https://bugzilla.redhat.com/show_bug.cgi?id=649955.

I've built myself a cairo10-1.10.2-1.fc13 by merging http://repos.fedorapeople.org/repos/...1.fc13.src.rpm with http://kojipkgs.fedoraproject.org/pa...1.fc14.src.rpm and the problem is resolved. I've suggested to the maintainer of the Firefox 4 beta packages that he might include the workaround in his bundle.

Thanks, everyone.
