[CentOS] 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, L?szl?

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

[CentOS] Constant screen flicker with Firefox browser
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?
