Adobe Photoshop 2020 update causing issues with Wacom Intuos Pro devices

[Shtajio]

PsUser Config is in place. 

Windows 10

Nvidia RTX 5000 graphics card

Has anyone else experienced this? Every time I place more than 3 brushstrokes on a document the brush makes a long mark across the page. As if the shift key is being held. Is there a fix for this?

Hi

You're not alone

I'd suggest you report it as a bug on the Adobe Feedback Forum

Hello everyone,

I've tried everything on this thread, and so far the only thing that seems to work is the solution that was on this link. It seems to be an issue caused by the smoothing option in the brush tools. if you et the smoothing to a higher integer than zero it seems to resolve the problem. Hopefully Adobe fixes this bug. But until then try setting your smoothing option to like 20.

I'm sure you not alone. However, all do not have your Problem.  My workstation has Windows 10 Pro installed and many versions of Photoshop  CS3, CS6,  CC 2014,  CC 2018, CC 2019 and PS 2020.  Therefore, I have my Wacom Intuos Pro configured to use WinTab API with all versions of Photoshop and windows INK for all other applications. And I configure Newer Version of Photoshop to use WinTap API for Pens via PSUserconfig.txt old Photoshop versions like CS3 and CS6 only have WinTab API support for Pens. My Display Adapter is a Nvidia quadro k2200.   I do not have problems using my Wacom Pen with Photoshop tools like brushes.

Some other setting I make for my Wacom Pen and Windows are Tip double tap distance Off. Pen  bottom button Alt+Right Click

Mapping to Display 1 for Photoshop and force proportions

Windows Pen and Touch I disable Press and Hold  Right Click settings by un-checking enable

Have you tried removing the PSUserConfig.txt file and checking "Use Windows Ink" in the Wacom tablet properties. I used to use WinTab but switched back to Windows Ink a version ago and have no issues.

That only applies to Windows 10 though

Dave this issue is affecting people using a mouse as well, plenty of reported cases so far, this thread in particular OP pointed out that the tablet works fine and only affects the mouse

I've seen those but most seemed to be using Windows 7

Most not all there was at least one Windows 10 user that reported  stray lines.

I'm sure there is at least one problem but no one has pinpointed where the problem is.  There could be more than one problem that may manifest stray lines.  Most did seem to be using Windows 7.

I had an issue with the older Intuos 3 pro, Windows update in October 2020 changed something with the driver. I had to uninstall the Wacom driver and reinstall driver version 6.3.11-4a. I had to have the tablet unplugged during uninstall and reinstall, once it was reinstalled the mouse caused a problem with it detecting the tablet I think so I unplugged the mouse and plugged in the tablet and success. The mouse does work after it finally detects the tablet and the driver I mentioned above was from 03/2015 intended for windows 8 but it works for getting this older tablet to get along with windows 10 for now. I hope this helps.

If you have an Old version of Photoshop installed you have to use WinTab API for CS versions of Photoshop do not have support for Windows INK.

Hi,

I have an iMac 2013, just bought a Wacom Intuos Pro Medium, and have been struggling for 2 days... Photoshop 2020 freezes, crashes, the pen carries the image all over, outside the canvas... just crazy. I'm very frustrated. I've been checking all forums and trying to get answers, but nothing until now... Anybody help me with that?

Did you have a SSD?
Photoshop is very laggy when the app or the files is in a HD!

Hi AndPeroty,

Thank you for your answer!

I'm OK now. I sold my iMac and bought a new MacBook Pro 16 inches... I thought a needed a better machine to be able to work well with Wacom and new updates from Adobe cc...

Thank you anyways!
