Photoshop makes random lines while drawing using the brush.

Hi @Anshul_Saini, thanks for the tips!

I followed your instructions, and the issue with Photoshop was only resolved when using Safe Mode or a different user account. However, in both of these scenarios, the Huion driver does not start — and in those cases, I don’t experience any diagonal line issues. This strongly suggests that the problem is directly related to the Huion driver.

Here’s what I’ve done so far to try to resolve the issue:

• Installed all previous versions of Photoshop.

• Tested my tablet in other programs such as Paint and Clip Studio Paint — it worked perfectly in both.

• Installed older versions of the Huion driver.

• Disabled Windows Ink for the tablet by creating a "PSUserConfig.txt" file in the Adobe folder.

• Changed the pen tip.

Hi @art_arthur, thanks for reaching out and sharing the screenshot — those diagonal lines definitely aren’t expected behavior.

Let’s try to rule out profile-specific or third-party interference. Please try the following:

• Create a new user account on Windows and launch Photoshop from there to test if the issue persists.

• Alternatively, boot into Windows Safe Mode and try drawing in Photoshop. This will help us check if background services or drivers might be conflicting.

Let us know the results — this will help determine whether it’s a system-wide issue or isolated to your current setup/profile. We’ll continue from there!

Best,
