Mixer brush leaving grean/blue glitchy streaks in everything no matter what

[icashootnstar3@gmail.com]

Whenever I try to paint with the mixer brush it leavs these nasty green streaks in everything that look almost like graphical errors. I've done everything from cleaning the brush, changing brush settings etc. and I can't get rid of it.

Try resetting the Photoshop Preferences. They can be found in the Photoshop menu on a Mac and the Edit menu on Windows. Within the General tab is the button Reset Preferences On Quit. This is a great general solution when Photoshop is acting weirdly.

I just tried that and it's still doing it

If it doesn't work you can try to fully reinstall photoshop:

The Mixer brush leaves a horrible rainbow graphical error whenever you try to use a brush with shape dynamics enabled. This is really a problem because the shape dynamics settings are very important to the functionality of some brushes.

HEllo, I merged your two threads on the same topic.

[PECourtejoie]

Hello, is it on 22.5? did you try to check the deactivate native canvas in Edit/Preferences/Technology preview. (then restart)

Also, I would try to right-click on the tool icon in the Option bar, and select reset tool.

I am having the same issue. Tried all the suggestions made here but no luck

[PECourtejoie]

Hi, please post the contents of Photoshop's Help>System Info... menu, so that we get to know your OS, its version, the exact version of Photoshop you are running, the date of the GPU driver, etc.

[Himaatwala]

Sure - the contents were pretty long so I am attaching them here as a pdf

There's something wrong with your driver for your GPU:

Driver: UNKNOWNDriver date: UNKNOWNDriver age: UNKNOWNDriver version: UNKNOWN

Install the latest driver and see the other troubleshooting here: https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html

[Himaatwala]

So I followed the instructions on the link you provided. It asked me to upgrade from Catalina to Big Sur OS - Did that. Then it asked to uncheck use graphics card in photoshop preferences and restarting PS. if the problem goes away then it is related to the GPU and its driver. However after doing all that the issue still remains.

The system info still indicates the driver as UNKNOWN. I am still not sure how to update just the GPU driver for the iMac. The instructions in the link don't make that clear

Had the same issue in minor volume when using mixerbrush with some kind of square brush. Most interesting was that blue color errors appeared only with my cintiq, but when using same tool with mouse - no problem. Anyway, in my case the problem was solved by deleting brush set and reinstalling it to photoshop again. 

[PECourtejoie]

Good info, @minivan were you on a Mac as well?

@Himaatwala icashootnstar3@gmail.com @timothyf37109604  are you still affected? which Ps and MacOS versions are you using? did you try the suggestions in the last post? try the mouse, update Wacom drivers? 

[minivan]

no, @PECourtejoie Windows10. Thanks)

[minivan]

No solution yet, avoiding mixerbrush on soft brushes. And yes, Im using wacom cintiq

[PECourtejoie]

@minivan do you have a repeatable case? A preset you could share to mr Tranberry?

Does your system info look normal, or do you also have the GPU listed as unknown?

Did you try "deactivate the native canvas" (preferences/tech previews)? (and a restart? )

Are native Rulers active (same preference area)

[tRdigrade]

I've had this issue for over a year with certain mixer brush presets. After reading @minivan's comment I realized that it only happens when using a wacom tablet. Still no solution to this?

[tRdigrade]

This happens on both my Win10 computer at home and a my work mac running Big Sur btw

[PECourtejoie]

Hi, @tRdigrade  I do not see rainbow lines artefacts in your posted image. Could you share one mixer brush preset that causes the issues? What about yous system info?

Did you try "deactivate the native canvas" (preferences/tech previews)? (and a restart? )

Are native Rulers active (same preference area)?
