P: Photoshop drawing random lines when using tools (Remove, Brush and other drawing tools)

Hello,

I am experiencing the same problem when using the Spot Healing Tool, Clone Stamp Tool. It draws lines and smudges them in my photo. I can’t work like this. Clients are waiting. Can you please advise about the status of this? Can we revert back to an older version of Photoshop?

This is happening to me as well. Updated Photoshop and beta. Using a desktop PC, windows 11 and 10 with my other PC. Nvidia graphics card on both desktops. Any fixes?

This is a known issue.

When using any brush type of tool (Brushes, Erasers, Lassos, Stamps, Healing) that tracks the the exact path of the tool on the document it will streak across the entire document at random. 

Demonstrated below with a lasso tool the Path Highlighted in Red.

Me: downloads latest Photoshop.  “Maybe that disappearing workspace glitch is finally patched.”

Photoshop: draws insane lines all over the screen on every initial brush and eraser press

Me: “Oh… okay then...”

It has been doing this to me for a week. I experienced this issue around when it was ever first observed, but the most subsequent update after that resolved it. It has now returned. It’s starting to genuinely affect my ability to efficiently do my job, and I have a lot of image editing tasks to do for clients on a daily basis. I’m having to report to my department head every day now that I’m experiencing delays. I ran a Ps update this morning and it hasn’t helped. Since I am on a work machine, the popular suggestion of just disabling other programs sharing my GPU isn’t entirely feasible. 

An update on this, as I had the exact same issue. I asked Gemini and it suggested going to my task manager and disabling any other software running which might cause conflict - this includes any screen capture overlay, graphic card software or motherboard tuning software. As soon as I disabled these, my Photoshop stopped having this issue.

For me I believe it was the motherboard’s Gigabyte Graphics Card Smart Tuner process causing the problem.

Unfortunately you haven't given us any information about your system. Therefore, all proposed solutions are a guesswork.

But it seems that’s possibly an issue with the preferences or with the graphic device.

First try to reset the Photoshop preferences

Remember to back up your settings before doing the preference reset

If this doesn’t help, try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

If it helps, you can check out the steps suggested here:   https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html

Check also if your system is up-to-date. Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. Please make also sure that you have installed the Studio version and not the Game Ready version of your NVidia driver.

If this all doesn’t help provide a copy of your 'System Info'. This can be get from the Photoshop menu item Help > System Info. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

photoshop version: 27.5.0

OS: Windows 11Pro

I’m mostly using the selection brush tool or the spot healing brush tool, but this issue is also affecting various other selection tools, healing tools, brush tools, eraser tools, and pen tools when I try to use them.

I’ll use the selection brush tool as an example. When I zoom into the image and try to highlight one thing like the seat of a chair, the tool also randomly highlights other parts of the image that I did not touch, mostly in the form of a single line, but sometimes multiple lines bouncing off the edges of the screen and forming whole shapes or blobs. The same thing happens if I try to use subtract instead of add. It’ll subtract random parts of the highlighted bits that I did not touch along with what I did. Since this problem is also happening with all those other tools, photoshop is basically unusable for me. I’ve tried resetting the tools, I’ve tried checking for updated, I’ve tried uninstalling and reinstalling the app and nothing has fixed the issue. 

When you use the lasso selection tool, click with your mouse on a place on the photo, many times it starts to select random figures. When this is not happening sometimes you can trigger it by making a selection and then delete this selection by Crtr-D. And then click left with the mouse on 1 place. 

I have test it on several versions. But version 27.0 is oke. The newer versions and the last one have this bug.
