Screen Tearing Test

If you see a shift or a break in these vertical black and white stripes that forms a horizontal line across the screen, that means you have screen tearing. The visual artifact that looks like the edges of the stripes fail to line up occurs when a video or a 3d game is not in sync with the display's refresh rate.

If you are not sure whether you have screen tearing or not check out my video with an example:

[WheatThinner]

imagine if someone made another video like this but just put a screen tearing effect on it, so evil😈

[kartoffelbaer]

very useful for debugging, thank you very much! "Force full composite pipeline" fixed it for me (in nvidia-settings under linux)

Sometimes it is only happening in a few apps. If that is the case, check if the app has hardware acceleration. Turn it on first, and if that does not solve the issue then open your graphics card control panel and turn on v-sync.

Fixed my screen tearing by looking at the GPU. I had one of the brackets that held it in place installed a tiny bit wrong and there was a screw that was pulling an entire RX 570 8 gig nitro out of the PCIE socket slightly. I am both appalled and amazed by the craftsmanship on this case, I truly am. That bracket is so poorly designed that it's incredible, but also fuck that screw is a CHAMP to pull a GPU that's fairly heavy out enough to see artifacts and screen tearing.

Nice video, after trying what was mentioned and it not working, I checked enable Hardware Acceleration in Firefox and Chrome Settings and that seems to have fixed it.

I have used this video as a sanity check for screen tearing while configuring a newly installed machine many times now, thank you.

Weirdly enough, since you explained it so well. I just went to my Intel control panel (through the Display section) and swapped my Scaling from "Maintain Display Scaling" to "Maintain Aspect Ratio" and it worked ! No more screen tearing whithout Vsync :D.

Anymore, because I watched your "How to fix AMD GPU Radeon screen tearing in Debian, Linux Mint & Ubuntu" video and fixed it, thank you very much!

[TanmaiNiranjan]

I literally got hypnotised trying to watch this

[vinayakviyer]

Olla dude! Much thanks, In my case on debian 10, the issue was a non int refresh rate. This helped me troubleshoot it though! Appreciate what you're doing, linux and open source needs more folks like you!

[yesitsdawid]

For the linux AMDGPU users out there, Run
xrandr -q
to get the name of your video output (something like HDMI-A-0 or eDP), then run
xrandr --output eDP --set TearFree on
replacing eDP with the name of your output

[Sfrags]

plot twist, he put a screen tearing effect on it

[Mateusbr]

I'm not having Screen Tearing, but everything is shaking, this happens a lot in videos and movies, especially when the image goes horizontally. I've searched in several places and haven't seen a question or even an answer.

[cuongdc_unreal]

I watched this video more than 100 times actually 😂😂😂

[nexoner]

Thank you for the test! Really helped me.

[isassin]

it feels like my monitor is trying REALLY hard to not let the bars tear

[Bryces-Vlogs]

thank you so much! i was going insane seeing it constantly and couldnt handle it anymore i did some research and your video popped up! i noticed it withing 5 seconds of the video and then restarted my PC and it seems for be fine now! Thanks alot!

[VioletRM]

thanks for the tool, had to run picom with its experimental backend to fix. much appreciated!

I found the solution! At least for mine.
Make sure your *display driver is up-to-date*
How to update your display driver (on Windows 7)


Open the Start menu.
Search Device manager---> Display adapter ---> right-click your driver ---> update driver software ---> search automatically for driver.
If there is a window pop-up "installing..." and then the screens get flicked, it means the driver is installing.
Once it completed, restart the computer and it's done.
However, if it says your driver is the latest, then it must be something else.
Good luck!
