Graphics error without reasons. I have only one question: why?

[nando_0309]

This problem has appeared some day ago and I don't know why. I didn't work on them recently and every graphics with this logo appear wrong. It's a firm's logo and I have a big problem.

I hope in your aid!

I think you'l need to post the actual illustration in order for someone to troubleshoot it.

Ok! Thank you!

In this file for example the shades doesn't do their jobs.

Does it work better in CPU preview?

So these are older files? How old?

[nando_0309]

This is new (edited some weeks ago). It worked well until today. Yes I see it correctly in the cpu preview.

CPU is correct - while GPU is not?

Then it's an issue between Illustrator and your graphic card. A driver update, a system update, something like that. Are there settings in the driver that you could change?

Hello @nando_0309,

Would you mind performing a clean reinstallation of the GPU drivers (Intel / NVIDIA / AMD) and setting the Graphics Preference to High-Performance for Illustrator (https://adobe.ly/3X05nm3) as Monika suggested, and checking if it helps?

Looking forward to hearing from you.

Ok, I have an intel uhd graphics 630 and I updated the driver, but it doesn't work. It hasn't particular setting in the managing window. So, I clicked on "reset settings" to previous version and on AI it's disapperead the GPU preview, I have only the CPU. I can't change it now if I want to try. But working with CPU preview it's all right.

Thank you very much everyone!

PS: I still don't understand why everything changed on its own!

Hello @nando_0309,

Would you mind retrying the GPU driver reinstallation by downloading the drivers from here (https://adobe.ly/4gCKAfn), checking the checkbox to Execute a clean installation when installing the drivers, rebooting the computer, and then relaunching Illustrator to see if it helps?

Also, try running Illustrator under a different administrator account (Windows) and share your observations.

Looking forward to hearing from you.
