Strange lines in Illustrator

[TLM 2024]

I'm having issues with strange lines on my screens since the last update for Illustrator 2024 and now have the same issue with Illustrator 2025. Is there a fix? Plus, not all of my art will show on the screen.

That looks like an issue between Illustrator and your graphic card.

Is there perhaps an update available for the driver?

Does it get better in CPU preview?

Or when you turn off GPU acceleration completely in the preferences (that is not a permanent fix, just to locate the source of the issue)

I thought it may be a driver issue, but not sure. I don't know what CPU and GPU are. Julie Daniels

It's what you toggle with that cmd+E shortcut.

Hello @TLM 2024,

I'm sorry to hear about your experience. Would you mind pressing the Ctrl/Cmd + E keys on your keyboard to check if it helps?

Also, kindly share the System Report for macOS (https://adobe.ly/4f9Usxg) / Windows (https://adobe.ly/3ADbTao) after uploading it to a file-sharing service like Google Drive/Dropbox/etc., so I can investigate this further.

Looking forward to hearing from you.

I am on a PC, but pressed control + E. It seemed to fix the issue.

That just turned off the GPU preview. That is not a permanent fix, because Illustrator might slow down considerably.

OOH. Thanks.

Hello @TLM 2024,

Glad to hear that resolved the problem. Would you mind confirming if you're on Windows or macOS or share the system report, so we can investigate further why you're having trouble with GPU preview in Illustrator?

Looking forward to hearing from you.
