As you have such new Intel Card (4th Gen Core) try to enable the SNA acceleration and also the TearFree option, might help.
First make sure that the folder /etc/X11/xorg.conf.d/ exist. ls /etc/X11/xorg.conf.d/
should return some values, or nothing, but if it will returns No such file or directory
you have to create the directory with sudo mkdir /etc/X11/xorg.conf.d
.
Now, execute the following command, as one command in your terminal (no matter if appears here as 3 lines). Copy-paste from here to your terminal.
echo -e 'Section "Device"\n Identifier "Intel Graphics"\n Driver "intel"\n Option "AccelMethod" "sna"\n Option "TearFree" "true"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf
It should ask for you password and after you write it (correctly), it should return this result
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
Now, restart the display manager or restart the PC and see the results, see if the problem fixed.
To restart the display manager, depends on which of them you are using.
Hit Ctrl+Alt+F2 , login with username and password and give the following commands
sudo systemctl stop lightdm
sudo systemctl start lightdm
If you are using another DM, user the appropriate name (gdm or lxdm ..etc)
