Constant Screen Flicker With Firefox Browser

Hi Guys,

I’m facing this issue: https://bugs.CentOS.org/view.php?id=8482

It came after upgrading to 7.1 and only Firefox is affected, Chrome is working.

What I’ve tried so far:

– Tried NVIDIA drivers 340.65, 346.59 and 346.72
– Upgraded Firefox to 38
– Tried Safe more / Refresh Firefox
– Tried to turn HW accel. off in Firefox

None of these has helped to eliminate the issue.

Do you know how to work this around?

Many thanks, László

  • It sounds like you are experiencing this problem https://bugzilla.gnome.org/show_bug.cgi?id=724788

    The fix is a two line patch that is released against clutter 1.16, but it applies cleanly against 1.14 (which is in CentOS 7, maybe this gets fixed with the upcoming Gnome rebase).

    I rebuilt the clutter rpms with the patch and the flickering problem went away.

  • Hi Thomas,

    Thanks for the hint.

    I’m trying to rebuild the original SRPM without the patch for know, but I’m getting the following error.

    rpmbuild –rebuild /tmp/clutter-1.14.4-12.el7.src.rpm
    … checking for XIAllowTouchEvents… yes checking for XIScrollClassInfo.number… yes checking for XkbQueryExtension… yes checking for GDK_PIXBUF… no configure: error: Package requirements (gdk-pixbuf-2.0) were not met:

    Package libpng15 was not found in the pkg-config search path. Perhaps you should add the directory containing `libpng15.pc’
    to the PKG_CONFIG_PATH environment variable Package ‘libpng15’, required by ‘GdkPixbuf’, not found

    Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.

    Alternatively, you may set the environment variables GDK_PIXBUF_CFLAGS
    and GDK_PIXBUF_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. error: Bad exit status from /var/tmp/rpm-tmp.o3QHFY (%build)
    …

    I’ve checked that libpng15.pc is in /usr/lib/pkgconfig. Tried to set PKG_CONFIG_PATH to /usr/lib/pkgconfig manually, but the error is the same.

    Do you have any idea how to work this around?

    Cheers, Laszlo

  • Hi Lazlo,

    To build almost any src.rpm package you will need some *-devel packages installed. And if you are going to modify a build you need to install the src.rpm into a build area first.

    http://wiki.CentOS.org/HowTos/SetupRpmBuildEnvironment https://fedoraproject.org/wiki/Mock?rd=Subprojects/Mock

    The spec file contains a set BuildRequires statements that will be a starting point. The clutter.spec file contains these:

    BuildRequires: glib2-devel mesa-libGL-devel pkgconfig pango-devel BuildRequires: cairo-gobject-devel gdk-pixbuf2-devel atk-devel BuildRequires: cogl-devel >= %{cogl_version}
    BuildRequires: gobject-introspection-devel >= 0.9.6
    BuildRequires: gtk3-devel BuildRequires: json-glib-devel >= 0.12.0
    BuildRequires: libXcomposite-devel BuildRequires: libXdamage-devel BuildRequires: libXi-devel

  • I am happy to build this an stick it in a non standard place where people who have this problem can get it.

    I will build the new clutter and link it to your bug now.

    Thanks, Johnny Hughes
