GPU glitch in Illustrator 25.3.1 weird corners/ jagged lines/ weird artifacts

[jan]

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.

Does settting the Precision to something small like 0,001 in the Pathfinder Options help?

Without seeing Layers Panel, Stroke Panel Appearance Panel and object selected it is very hard to say.

• Are there strokes involved?
• Are these real paths? Check it with [Strg/Ctrl]+[Y]  (Outline View)
• Is this a problem with GPU? Try to toggle with [Strg/Ctrl]+[E]  (Preview on CPU/GPU)

Thanks a lot. It was in GPU Preview, had no idea that would mess with the geometry like that. Anyways, thanks a lot for the quick reply!

Hi.

I think something changed in the code of the boolean functions. There is an example that I have used in my classes for more than ten years, and last Thursday, the result was disastrous. I had to stop the class and record a video after I discovered how to solve the problem.

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?!

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.

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).

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. 

[Ton Frederiks]

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.

[Patrick Guillermo15C2]

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. 

[Ton Frederiks]

Then it is just a preview glitch.

[Patrick Guillermo15C2]

Hee Tom,.. it is strange i have really never noticed this?! Is it gone when i am going to send this to a printer?

[Ton Frederiks]

It will be OK to send it to a printer, it is a GPU preview problem.

Using the power of your graphics card, Illustrator can speed up the display.

Unfortunately speed does not always mean accuracy.

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

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

[Rikky1902]

I have the same problem and tried it but it's still the same

All vector lines are highlighted in red.  No stroke.  Moved accender on "N" and illustrator keeps glitching out.  Can't get rid of it.  Any suggestions?

I need to send the client a proof but I can't because of this glitch.

Please try View > Preview on CPU

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??

[marliton]

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.

Hello,

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

Thanks

[J E L]

@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.

[defaultnej2ibujqdg2]

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!

Do I see right? 3 objects: 2 triangles and one rectangle? Can you share screen shot before using pathfinder?
