I have recently installed Lubuntu and everything works fine except there's this problem of my screen breaking when there's a lot of movement on the screen. It happens a lot when I'm watching a video. I'm attaching a link to an example below. Also, the tearing happens at the same position always.



  • What's that hopping window? Did you move it or does it move on itself?

  • I was scrolling it to show the effect take place. It only happens when there's movement Jun 16, 2018 at 20:35
  • You mean the Z shaped lower border of the black part? I'd guess that's quite normal when moving windows that quick.

  • I know it's not normal because it works fine in Windows. When I'm watching a movie for example, it occurs alot and is a bit disturbing Jun 16, 2018 at 21:15
  • Shearing happens. Vsync is a thing you can tweak for some video cards on the linux side of the house. If you juggle a video window, it's going to happen. I'm running an underpowered intel onboard video chipset, and I don't get shearing as long as I don't have a great many tabs open. Not a bug or issue. Usage forcing a behavior resulting in complaint.

I had the same problem with Ubuntu 19.10, and the above-accepted answer didn't work for me. After my investigation, I found this ArchWiki page where this issue is addressed and solved. If you have are on Ubuntu distro, you have to read this.

TLDR; do this if you don't want to read the link I have mention and directly solve the problem:

    sudo mkdir -p /etc/X11/xorg.conf.d/
    sudo nano /etc/X11/xorg.conf.d/20-intel.conf

And add this lines:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"

And exit the file. You might have to reboot.


I fixed it by installing compton:

sudo apt install compton

And adding this code to run every time the session starts:

compton --backend glx --vsync opengl
  • @shahlin_lbrahim can you exaplin it a little bit more? What does Compton do? Why does the code, you mention do? It will be helpful for the user who is having this issue. I have the same issue in Ubuntu 19.10

  • @Prabeshbhattarai Hey, not sure why it didn't work for you but unfortunately I no longer use Lubuntu or faced the issue ever since, so I can't provide enough information. Hopefully your answer works for others! Dec 1, 2019 at 16:36
