Same here. Impossible to work with. As soon as I zoom, the canvas flashes and GPU acceleration turns itself off. After a while, it even keeps turning itself off directly after starting Illustrator. Without acceleration, everything is super slow on my 4k screen and the zoom tool sucks (and lags like crazy).

I think the main trigger is for this is the presence of raster effects in a file. I have one file which I simply cannot open without the GPU renderer ******** itself. But after removing any raster effects from the file, it seems to be working.

I have having this issue aswell. The GPU preview disapears and my zoom tool is all *********. Please fix this

This issue seems to have gotten worse with the last update. Reopening the file fixes it until you start zooming around again. This is a huge time burglar, and we have deadlines. Worse with hi-res bitmap images.

This bug is super annoying. It makes it almost impossible to work with illustrator. It happens mostly when I'm working on a CMYK mode

I remember this issue was resolved in past versions of illustrator, but not sure why they bring this back in the latest release.

Same on 26.3.1 on M1 2021

Illustrator can't handle outline mode and disables GPU.

How is it that adobe makes illustrator worse by each update? how can it be that outline mode (the lightest possible way to view vectors) completely renders the application useless?

RIP my time, energy and mental health troubleshooting, reading forums and ******* head against the wall

Same here. But at least was able to reset the GPU support by restarting the software. But it's still "pain in the a**".

I'm on the latest version and the issue still persists :(

This still isn't fixed in 26.2.1 and despite all support articles claiming it's resolved. Here's a video with a view of all settings, activity logs, etc. Please fix this, as it really makes Illustrator unusable: https://www.youtube.com/watch?v=ZBcTKuZ-lQs

If you have GPU Tuning Software like RivaTuner/ Afterburner / GpuTweak, you must shut it down first and then restar Illustrator.

I am getting the same error in the current version of the Illustrator. Please help!

That is not the first time I get annoyed from Illustrator and search relief in the uservoice.

But it's certainly the first time that I read there is a patch waiting for me in CC that fixes my current problem.

Well played, Adobe... Keep it up. ;)

I just installed the 26.2.1 update and it only fixed the issue with changing to outline mode. But this bug still occurs if I turn on the rulers or attempt to edit the artboard dimensions.
I just did a few tests by creating new files in both CYMK and RGB.
The bug still has a permanent effect to the file. But I have discovered that if I save it to my Creative Cloud storage and then immediately download via a browser the file will start using the GPU again, until I need to edit the artboards or turn on the rulers.

Hallujah! Bug fixed for me in version 26.2.1
Thank you!

Still have the same problem on the 26.2 beta.
I have a 2 monitor setup with my windows desktop, one is 4k, the other 1080p. The problem exists on both screens but maybe having one 4k screen plugged in makes the problem happen no matter which moniter illustrator is on.

This is probably not very helpful but I did notice is that there is no problem if it is a blank document with not a single graphic on it.

Adobe - my apologies!

I've only just had the pre-release tab become available in my Creative Cloud desktop app. I've installed Illustrator pre-release v26.2 and confirm the bug has now been fixed. Thank you very much :)

Do you know when 26.2 will go into full release?

Thanks :)

OK Adobe, please take notice of this because myself and another user think we have got further to the bottom of this issue which has NOT been fixed in 26.2 Beta.

The problem appears to be with screen resolution on Windows platforms. This affects both laptop screens and external monitors and appears that resolutions higher than 1920 x 1080 are subject to the bug that affects GPU preview. Working at 1080p on any screen is absolutely fine - no issues.

But come on - who in the professional graphics industry is seriously working at 1080p.

Please can we get this screen resolution issue sorted ASAP as it is a real productivity killer having to close and reopen documents to get our GPU zoom and drag back!!!

Ok, I've done some more thorough testing on my system and can confirm (for me) that the 'fixed' 26.2 Beta exhibits exactly the same behaviour as the 26.1 full release i.e. I still have the problem.

However here are some behaviours I can explain.

I run Illustrator on a Dell Alienware 15R3 laptop, that has 16GB RAM, Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, Nvidia GTX1060.

When I run Illustrator using the laptops built-in screen @1080p everything works absolutely fine. When I run Illustrator whilst using my main work monitor which is an LG 27" LED display running @2160p UHD, the screen preview will NOT return to GPU preview after switching to outline mode. However, if I start Illustrator from just my laptop screen, then switch over to my external monitor using windows+P it all works fine. So this is a kind of workaround BUT, I never had to do this workaround before and always just used my external monitor with no issue.

So it looks like this bug has something to do with using an external monitor with a laptop on Windows 10?

Hope this helps shed some more light.

Just updated to 26.1 and this issue has instantly returned. Rolled back to 26.0.3, unfortunately I didn't make a note of what version I was on before updating.

This seems to have solved the GPU preview issue, but rolling back has removed all my preferences and workspaces despite having the checkbox to preserve settings marked for updates.

I really don't like to complain in public forums but this is seriously frustrating as an issue from 2 years ago is still costing me work time.

Hi same issue here.
(also cannot change color profile to North America as I only have Europe available)
To help a bit, if you go to window, open in a new window, it's back to normal
