Yes, I can see that tearing in the attached screenshot also, I have tried testing it out at my end and its working fine.
Please let us know which brush preset are using in Photoshop CC 2018, also you may try and reset the Photoshop preferences and check if that helps. Refer: Preferences in Photoshop
It seems to occur with all the brush presets that I have tried using. I have tried resetting the preferences but it does not seem to help. Even reinstalling Photoshop did not fix the problem unfortunately.
Have you ever noticed this issue in the previous version of Photoshop? Is it possible for you to share your workflow with us.
I haven't noticed this in previous versions I have used.
I'm sorry, I'm not quite sure what you mean by sharing my workflow?

This is probably the worst update since CC came about in regards to bugs that need addressing. I ran PS CS6 recently on a tiny i3 8GB with onboard graphics and the application ran like an absolute dream. Today I'm producing a movie poster on an i7 4790k 32GB GTX970 using PS CC 2018 and the application is running like an absolute dog.
this seems to be a bug with the ruler tool. press ctrl+r to bring up the ruler in full screen mode to have this tear go away. you will have to deal with having the ruler on your boarders at all times but its better then the tear IMO. let me know if this helps bud
That seems to have fixed it, thank you!
Let me check with the team.
Thanks for providing a workaround for the tearing issue you're seeing.
I haven't been able to reproduce this, so any steps you can provide towards reproducing will be helpful.
Which version of Windows 10 is being used?
Are the GPU drivers up to date?
Does it still tear if you disable the GPU? Troubleshoot Photoshop graphics processor (GPU) and graphics driver issues
I am on Win 10, version 1703 (15063.674). I have not updated to Windows Fall Creators Update on my current machine, because the update brought more bugs to Photoshop. Running a GTX1080 GPU with the latest drivers. The tearing is not very obvious at first, but pretty noticeable on diagonals. It does not seem to persist with GPU acceleration disabled. Also: picture (in between the black verticals):
You wrote, "It does not seem to persist with GPU acceleration disabled".
Good to know that disabling the GPU helps, curious if this is the same for others as well?
You could try the later suggestions in that same article to re-enable the GPU, and try adjusting the GPU Drawing mode to Normal or Basic, and/or toggling some of the other "Advanced Settings" found in Preferences > Performance as well. Let us know if any of these changes make a positive difference.
If you could also provide Photoshop's > Help > System Info dialog text, that could help us further diagnose as well.
You can use a service like pastebin.com to share the long text via link.
Hi again Pete,
I'm afraid toggling the different modes and settings of GPU acceleration does not seem to help, only switching it off entirely does... However, choosing between screen tearing or no GPU features in PS is a tough call.
Thanks for sending me your System info privately Lundmark.
Mostly things look pretty good there, drivers are up to date, nothing looks too out of whack.
I'm checking with the team on this one, but am curious if the "tearing" actually saves to the file?
Save a file that displays the tearing.
Disable the GPU in Photoshop and restart Photoshop.
Reopen that file that was saved.
Is the tearing still in the document?
We're attempting to figure out if this is a GL display issue (better), or if it's actually affecting the pixels in the document (worse).
Let me know how that goes.
Hi there. I've been encountering this issue as well and I thought I'd throw-in what I've noticed in the bug's behavior. I've also included a screen-recording for aide.
Long story short, from what I'm seeing the tearing happens in the middle of the actual screen when Photoshop is in full-screen mode and has no effect on the document itself. The tear will remain in the exact middle of the screen in FS mode, no matter where the document, or any of its contents, are. Turning the rulers on while in FS mode will remove the tear, but (at least in my case) it also makes the program extremely laggy.
S'about it. Hope this is able to help.
Thanks for the helpful video Nathaniel. Does the tearing stop if you disable the GPU in Photoshop's Preferences > Performance?
Give the steps a try on this page, and let us know if you continue to see the tearing with GPU disabled, or by adjusting the drawing mode (located in Performance > Advanced).

The issue persists even after trying all of the steps you linked, as well as switching between drawing modes. However, disabling GPU does indeed remove it! My GPU is as up-to-date as I can make it, but I'll throw my system/driver information down below in the hopes that it will lead to the downfall of this troublesome little guy.

Thanks for the added detail Nathaniel,
The driver for the GTX 960 does look to be most up to date. That driver was released on December 20th, 2017.
You *could* try downgrading the driver to the previous driver version (such as version 388.59, released Dec 7th) and see if that helps. Otherwise Disabling the GPU would be the best bet until a driver without this issue is released.
