Bonjour,

Quand j'utilise l'Outil Correcteur Localisé en cliquant avec ma souris sur une zone de la photo à l’écran, une multitude de lignes partent dans tous les sens. Donc cet outil ne fonctionne plus depuis plusieurs jours. Est-ce un bug ?

I was having the same issues with multiple tools in Photoshop. Finally after a day of trying all things, we have found a solution on Reddit. I tried it and it fixed it right up. This is for PC only.

Create a text document with Notepad. Name it “PSUserConfig.txt”
Write “UseSystemStylus 0” in the text body (that’s a zero not an “O”)
Save it in “C:\Users\*YOUR USER NAME*\AppData\Roaming\Adobe\Adobe Photoshop 2026\Adobe Photoshop 2026 Settings

(In step 3, *YOUR USER NAME* is unique to whatever your username is.)

Restart photoshop and the tools should work again.

Credit to u/Professional_Use442 on Reddit for sharing this fix. Note: If you want to use the stylus again you’ll have to follow their instructions on how to re--enable the stylus mode.

It could be an assortment of reasons -- dirty mouseball (if present); battery low on a wireless mouse.

After the first click, does everything between clicks “connect,” that is, as TVO says something is keeping the eraser stuck in the on position (like, the Shift key)?

Thanks, but none of these are my issues. It’s definitely the software bugging out. It’s usually the first click that goes haywire. If I can click a bit off of the image I can then go about my work. And then other times it’s constant. Tried new keyboard and mouse.

I’ve seen this happen when your shift key is stuck. Easiest thing to try is unplug your keyboard and see if the eraser tool does the same thing.

Thanks, but that didn’t work.

I click once and it erratically draws eraser lines all over. Sometimes it will stop after the first click and work normally again, but I can't go back and undo the random erasing without the problem starting all over again. Working on PC with a mouse.

This is making photoshop completely unusable.

Do you use the mouse or do you use a graphic tablet?

Please 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 a text file and attach it to your next forum post.

My System: Intel i7-8700K - 64GB RAM - NVidia Geforce RTX 3060 - Windows 11 Pro 25H2 -- LR-Classic 15 - Photoshop 27 - Nik Collection 9 - PureRAW 6 - Topaz Photo AI

I've tried every possible solution, but the same issue keeps happening. Is my only option at this point to wait for a Photoshop update?

1.Reset All Tools

2.Create a text document with Notepad. Name it “PSUserConfig.txt”.

Neither of these methods worked

My system is Windows 11 Pro, version 24H2. After downgrading and installing version 27.0, everything works fine, but I can no longer use the latest AI tools. I really hope this issue can be fixed as soon as possible

@SimoneHanby try resetting the tools

If that doesn’t help, try manually resetting your Photoshop preferences

Why is my selection brush tool highlighting areas I haven't selected? I go to apply the brush tool to an item I want to remove, and it automatically selects random areas of the entire image. I’ve tried googling to find the answer and no luck. I even tried chatgpt. Help please, it’s driving me crazy! Simone :-)

Hi @SimoneHanby, Thanks for reaching out! Please take a look at @Ged_Traynor’s recommendation. You can also follow these steps to try manually resetting your Photoshop preferences: https://helpx.adobe.com/ie/photoshop/using/preferences.html#Manuall. Remember to back up your settings before doing the preference reset: https://helpx.adobe.com/ie/photoshop/using/preset-migration.html.

If none of these steps work for you, let us know, and we can continue troubleshooting. I hope this helps! ^CH
