Lagging graphics output

I have a ThinkPad T440s with an "Intel Corporation Haswell-ULT Integrated Graphics Controller" and Fedora 20 running on it. In general it works, but when the graphics output changes rapidly (e.g. scrolling or watching a video) there appear some weird lines for a moment. It looks like a broken image or something with a cut.

I thought the display panel is broken but the same behaviour is observable when connecting my TV over the mini-DisplayPort.

So it may be some driver related issue?!

Someone with suggestions?

I strongly recommend the RPM Fusion drivers for intel (mesa). You may want to follow this steps:

su -c 'yum localinstall --nogpgcheck'
sudo yum -y update
sudo yum -y install mesa-dri-drivers mesa-libGLU
su -c 'yum install libtxc_dxtn --enablerepo=rpmfusion-free-updates-testing'
sudo yum -y update

If you are running 64-bits version add this steps before update:

sudo yum -y install mesa-dri-drivers.i686 mesa-libGLU.i686
su -c 'yum install libtxc_dxtn.i686 --enablerepo=rpmfusion-free-updates-testing'

Then reboot.

Basically you are upgrading to the latest mesa drivers available.

Thanks for your answer. RPMFusion, mesa-dri-drivers and mesa-libGLU were already installed. So I only needed to install the 32 bit versions and libtxc_dxtn. (rpmfusion-free-updates-testing contains no newer version than the stable repo). Unfortunately that doesn't fix the issue. :( Nothing changed...

After a little research i found that 3.14 Linux kernel have some issues with some Intel Graphics new controllers. It's solved in 3.15. Also, it have a Intel technology called "Intel SpeedStep" that try to save battery regarding performance (sorry for my english here); You may start your laptop with the AC power connected to have better performance.

ok thanks. AC power does not make any difference but I will expect the 3.15 kernel :)
