According to Wikipedia :

Screen tearing is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. If you are on Debian or Ubuntu, and you have an AMD GPU this might fix the problem 😊

1. Check if the is any config

ls -l /etc/X11/xorg.*

{{< highlight bash-session >}} $ ls -l /etc/X11/xorg.* total 4 -rw-r--r-- 1 root root 108 Jul 30 11:33 20-amdgpu.conf {{< /highlight >}}

Backup if found

mkdir ~/xorg-backup
sudo mv -v /etc/X11/xorg.conf ~/xorg-backup/
sudo mv -v /etc/X11/xorg.conf.d ~/xorg-backup/

2. Check if the is any config

lspci -nnk | grep -i -EA3 "3d|display|vga"

{{< highlight bash-session >}} $ lspci -nnk | grep -i -EA3 "3d|display|vga" 09:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne [1002:1638] (rev c9) Subsystem: Gigabyte Technology Co., Ltd Cezanne [1458:d000] Kernel driver in use: amdgpu Kernel modules: amdgpu {{< /highlight >}}

If you have amdgpu then

create the config file

sudo mkdir /etc/X11/xorg.conf.d
sudo vi /etc/X11/xorg.conf.d/20-amdgpu.conf

Add the following to the config file 20-amdgpu.conf

Section "Device"
        Identifier "AMD"
        Driver  "amdgpu"
        Option "TearFree" "true"
EndSection

If you have Radeon then

create the config file

sudo vi /etc/X11/xorg.conf

And add the following

Section "Device"
        Identifier "Radeon"
        Driver "radeon"
    Option "TearFree" "on"
EndSection    

3. Reboot 💣
