Video has a line when fast images and scrolling is bumpy

Hi, so I am totally new here and very happy with this new linux experience so far apart from the fact that my xps 13 7390 2in1 isn't supported. Meaning finger print doesn't work, or at least I haven't figured out how and sliding my fingers back in a browser doesn't go back a page. I can live without that, even though it would be nice if this was fixed. But my main issue is that when I watch a video and the images moves fast I get a break in the video. Like a line that splits it in half. I found this video on the topic but that didn't work. How to Fix Intel Graphics Horizontal Lines Tearing Bug in Debian, Linux Mint and Ubuntu - YouTube Although I am assuming it is something similar.
I also noticed that when I scroll the youtube page it isn't a smooth scroll. It has little hick ups. Seems to be on other page with video content too. Any help would be much appreciated.

Can you please open a terminal with the keyboard shortcut ctrl+alt+t or from the App Menu.
In the open terminal, please paste the command:

sudo lshw -C video

Copy and paste the output here. This way we can take a look at the drivers in use.

The output of


may also be useful for checking your Refresh Rate.

Okay, So most of the fingerprint hardware isn't compatible with any Linux, So don't bother about that. Can you please tell me your video driver (NVIDIA / AMD), Cause it looks like a graphic problem.

Good Morning,
thank you for helping me here.

Yeah I figured that and it didnt even work well on windows. So I am not too worried about that. If I check for additional drivers under software & updates nothing shows up. This is what I found under the about tab: Mesa Intel® Iris(R) Plus Graphics (ICL GT2)

Hope that helps.

Notebook computer, 60hz... Pretty normal.
It looks like you are not using a Nvidia card.

Can you please add the grub parameter i915.enable_psr=0 and see if that helps resolve the issue:

sudo nano /etc/default/grub

Look for the line that looks like:


Place the above parameter so that it looks exactly like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

Tap ctrl+x to exit the document editor, then the y key to say Yes to save, then the enter key to save the current configuration.
The terminal will revert to normal.
Now you must run

sudo update-grub

in order for the changes to take effect.
Reboot and test...


I did all of the above and it seems better but it isn't completely gone. I don't notice the strange split when I am scrolling video pages like youtube anymore but I am still noticing a little break watching a video.

I am using brave and have a VPN running, if that makes any difference.

You also could try:
and see if you get better results. If you run into trouble, tap the esc key starting at the motherboard splash screen to pull up the Grub Menu. Select Advanced Options for Zorin > Recovery
Arrow key to the last option to Drop To Prompt and use

sudo nano /etc/default/grub

to revert the changes if needed to restore access and functionality. Be sure to remember after each change to run

sudo update-grub

for the changes to take effect.

Ok, so I tried all three options but none of them have solved the problem completely. I feel that the first option did the best job but it wasn't 100%.

Q: what is the motherboard splash screen?

Any other ideas of what I can do?

I just pressed the ESC key when booting my laptop and all I see is grub. Grub grub no commands that I can press?

I tried putting in the advanced command but it just returned can't find command

Can we test:

sudo nano /etc/default/grub




GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Tap ctrl+x to exit the document editor, then the y key to say Yes to save, then the enter key to save the current configuration.
The terminal will revert to normal.
Now run

sudo update-grub

Reboot and test...
If that helps the issue, it at least gives us some idea of what is going on.
You will see higher power consumption and less acceleration in this mode.

For now, we are testing one aspect of the Graphics driver, so we can ignore that loss of screen rotation temporarily.
Can you test videos?

Yes. I have to come back to this in an hour or so. But so far it looked normal.

Ok I tested a bit more and the video seems to work just fine. On second thought it is still causing the line when it is a fast moving image.
Also when I change from full screen to small the browser was blacked out in corners. Once I go over it with the mouse it is back.

Ok... So it appears this may be a known upstream bug.
I wonder if the linux-oem-kernel may function better.
What result do you get from:

sudo apt install linux-oem-20.04

Ok, i did that and no real change. The line is still there.

What result did you see in terminal when you ran the installation?

It downloaded the whole program and then i rebooted it...

Did you use Advanced Options for Zorin from the Grub Menu to select the kernel to boot from?
