Since the latest update I get weird effects when using pathfinder (trim/divide) for instance. Is there any know issues? Se attachements. The object when using divide gets weird corners, what am I doing wrong? Never seen this before. Any suggestions? Thanks.

Hi all,

Sorry about the inconvenience this issue has caused. We are currently investigating this issue. Till the time it is fixed, please try the workaround shared by @pixxxelschubser
Turn off GPU performance from Illustrator Preferences (CMD+K > Preferences > Uncheck GPU Performance).

I would also request you to upvote this issue here ( https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/43599609-sharp-corner-edge-displaying-wrong ) and stay tuned for updates.

Dans la version 2021, et uniquement sur cette verion, lorsque l'on dessine une forme arrondie, sans contour, la pointe se prolonge par un rectangle. Pièce jointe. Merci d'avance

Probably a preview problem.

GPU Preview is fast, but sometimes inaccurate.

Try switching between GPU/CPU Preview with Cmd or Ctrl E.

Hello! I am currently using the latest version of Illustrator. I notice that the semi-transperent contours look very srange. What is the problem? Where do the broken lines come from?

This may be a side-effect of GPU Preview. Try "View Using CPU" to see if the issue is corrected.

Is this happening to anyone else? This is a newer problem I'm experiencing where the point of an object doessn't actually come to a perfect point. There's no way for me to edit this little edge as the object is fully expanded and has no stroke. You can see it happening on most of the letters and the star shape in the Q.

Sorry, I originally uploaded a different file that showed the specific edge I'm speaking about. I'll include a screenshot so you can see what I mean. This weird edge is showing up on almost all of my points on each letter as well as the star shape included in the file I originally shared.

Hello,

When I use pathfinder (minus front), the forms makes an undesirable corner.
How can I fix it?

Thanks

@defaultnej2ibujqdg2 Could be several things but I'm assuming you already checked your layers panel to make sure there isn't another shape you didn't delete underneath the forms. Is that little corner showing up when you export the file? Next will be checking your GPU settings and possibly a preferences reset. Let us know what version and OS you are using and if you need more troubleshooting help.

Hi,

The little corner disappear in CPU mode and is not there on an hi-res pdf.
I'm using MasOS Mojave and Illustrator 2021 (25.3.1).

Thanks for you time and answer!

Hi there i found a very annoying BUG. When you try to split a circle with the pathfinder tool, he adds a little extra on the tips of the stroke. Please help me to solve it.

Try if it is still visible when you switch to CPU Preview (Cmd or Ctrl E)

And/or set the pathfinder precision from the panel menu PathfinderOptions to a small value like 0,001 pt.

Heej Tom setting the precison to 0,0001 did not made any difference. However it is indeed not visible when i switch to CPU preview.

Recently updated iMac (27-inch, Late 2012) to latest software along with illustrator, measurements now do not have live displays and are replaced with grey boxes whenever using pen tool, line tool and box draw tool.

I have seen that it may be due to my graphics card but havent had this problem before?

Is my mac now out of date??

Community Expert

Hi. Make sure that the Graphic Card has the latest driver available installed. Also, disable "GPU Performance" in Preferences > Performance and check if the issue persists.

I get this exact same issue since an update around this time... I'm using a iMac Pro with 32GB RAM so it really should handle this kind of stuff...

I found that switching off GPU Preview fixed this as well but now Illustrator is unuseably laggy since the update.

Is there a better solution?!

Participant

Had the same problem here.
Happy to found the solution here but quite annoyed with team Illustrator as I don't understand why the option of GPU Preview is still in (for many versions) as it's causing these issues. If it doesn't work; trash it. Sorry had to vent.

Community Expert

It is a tradeoff between speed and accuracy and a work in progress.

I like the speed and switch temporarely between CPU and GPU when I don't trust the preview (Cmd or Ctrl E).

Any one can solve this white patches in Illustrator (100pt stroke used)

Have you tried switching from GPU to CPU in your viewing options?

Has anyone else experienced a fault with gradients that appears to cause a fractal effect? Here's a couple of screenshots...

Now, I've only encountered this parasite when working with outlined type. I can make complex shapes without any fault in the same gradients.

Colour space is CMYK as this needs to be for print. Exporting to pixel formats makes everything right. SVG files inherrit the fractal effect.

Any thoughts?

Hi there,

Sorry for the trouble. Could you please share some info like:

The version of OS and Illusrator?
Is the issue related to a specific document? If yes, could you please share the document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link.
Have you tried toggling GPU Performance under Preferences > Performance?

Looking forward to your response.

Thanks & Regards,

Hi Anshul, thanks for getting back to me.

I can confirm I'm using macOS Big Sur version 11.4 and Illustrator 25.3.1.

The fault appears in new and old documents and does not appear to be colour space specific.

My settings have GPU Performance activated. Toggling to "Off" solves the problem! Confirmed by it reappearing when GPU Performance is activated again. How bizarre?!

To clarify, GPU Performance has always been active. I use gradients most of the time in my work and the fault has only appeared in the last update or two.
