Performance is extremely slow when using show grids in outline preview
macOS Big Sur 11.4, Illustrator 25.3.1
When switching to outline mode when using show grids, it is almost impossible to keep on working as everything is in slow motion, as if the graphic card is unable to cope. This occurs with a 500 kb file that was trouble free before the last updates.
It turns out the problem is fixed only partially in 26.3.1, only for some users, and the performance remains slow when grid is rendered with lines or dots in Outline mode. This applies to zooming, panning and ghosting of objects being moved.
Please help the team by providing your specs and answers to these questions:
1. Does it work fine with grid as dots in Preivew / Outline mode?
2. Does it differ from grid as lines in these modes?
3. What is slow for you exactly? How severe?
4. Is there a difference if you disable 'Grids In Back' option?
5. What are you lines/subdivisions settings?
And any other related feedback is appreciated. Let's track it down and get this really fixed.
Thanks for all the feedback and thank you Anki for the tip!
I've found that simply deselecting the "Grids in Back" preference seems to work.
I can confirm - for me at least - that unchecking 'Grids In Back' under Guides & Grid in Preferences works and stops the lag.
So worth trying if you haven't already.

Follow-up from my earlier post: I tried to set up a whole new document and copy over the icons. Which worked fine, as the pre-set grid was much bigger. As soon as I set the grid to 1px X 1px, the same problem occurs.
I then proceeded to try all sorts of different pre-sets, and the 1 px grid is the problem (as I have seen mentioned before in this thread)
What works for us now as a workaround (we need a pixel grid and the 'show pixel grid above 600% zoom' doesn't seem to do anything), is (after many, many trials) to set the grid to 2 px with 2 subsections, and uncheck 'Grid in back'
This has cost me a whole day of work (including many crashes and hours on the helpline), but I hope it helps other members in the community. Attaching screenshots in English and German.

I (and my team) have had this same problem for months now. We are working with a large icon file (each 24x24 pixels, optimised for as few anchor points as possible, pixel perfect, set on a pixel grid). Most of the icons are monochrome. The file was only 3.4 MB. Originally, we had over 600 art boards, and over 55 K anchor points.
I had tried all the recommended tricks, like switching from CPU to GPU view, etc. (but that made the zoom laggy). Today I spent more than 2 hours in the adobe help line, and gave various support staff access to my computer, where they tried a lot of things, deleted presets, and increased scratch disk memory. The problem persisted. I was then told the file was too complex, and there is nothing more they can do. And that I needed to reduce the number of anchor points, but they couldn't tell me to what number.
I proceeded to simplify the file, achieving a file size of 1.9 MB (!), 480 artboards and 49 K anchor points.
Sadly, the problem persists, and Illustrator immediately crashes when I try to show the grid in line mode.

Intel UHD Graphics 630 1536 MB, which I was told is plenty powerful for any Adobe app.
I would really appreciate if Adobe could fix this soon, as I cannot believe a 1.9 MB file can be the cause of such a massive problem. Thank you!
The default for the grid in the preferences is 72pt, but the more detailed the settings, the slower it runs, and it seems to hang at 2pt.
Same here on Windows 11 (and latest win 10 pro too), Illustrator 26 (latest release)
This is extremely blocking for work and frustrating for system as it makes the whole PC lag.

This is still an issue in Illustrator 26.0.2. If “Grids in Back” is on in Preferences, and grids are turned on from the View menu, the entire app is unresponsive for many seconds at a time. Illustrator becomes completely unusable, even with an empty document. For me, it doesn’t make a difference if I’m using the dot or line grid line style.
The issue is reproducible on two different Macs (one Intel, one Apple Silicon), and has been present across Big Sur and Monterey for me.
Bought new fancy mac pro yesterday with Monterey OS, installed new Adobe Illustrator from scratch, the same lag with grids still there :(
Issue happens when "Grids in Back" is turned on.
Update - issues is back after a few days. The only way around it for now is to switch to 'view using CPU' in the view menu. Now v26 has been released - what new bugs are in store I wonder?
I contacted Adobe Support via the chat box about this - they needed to remotely access my computer, check various things including fonts , re-set preferences and maybe a few other things - sorry I can't be specific. It took a while but they got it working again and now outline and grid view behave as they should with no lag. So it's worth contacting them to get it resolved.
Same for me too - Illustrator 25.4.1 - Mac Mini late 2012 running Catalina. If show grid is turned on and then you switch to outline view, Illustrator will become seriously unresponsive, taking many seconds to respond to any mouse click, moving objects, zooming etc, sometime it almost freezes entirely. When turning off the grid or switching back to preview the problem goes away. This has never been an issue in earlier versions of Illustrator.
Try changing grid style to dots — it helps until this bug will be fixed.
Same here, illustrator 25.4.1
If i hide the grid everything is fine, but i do need the grid.

hopfully they resolve this fast cause it's a pain in the a...
Same. Why so little votes? Is this such a rare bug, or does nobody uses grids in Illustrator v25?

The same thing here. My macbook overheats and slowdown so much, is really stressful to work like that.
Same here - Catalina and illustrator 25.4.1 on macpro 2109
Showing grid makes illustrator useless slow, when hiding, it works fine.
I should have mentioned that if I hide the grid I can successfully view in outline mode.
When trying to view outline mode (command-y) with an illustrator document that has a grid, it locks up illustrator and I get the beach ball balloon and "Illustrator not responding" so I have to force quit.

Having the exact same issues here!

In Illustrator 2021 v25.x, if you turn on the grid in the view menu in an illustration and then switch to the path view via Command + Y, it takes a long time for the path view to appear, and Illustrator hangs afterwards.
I have been tinkering for a long time to make this connection.
The bug appears in versions 25.3, 25.3.1 and 25.4.0. I cannot say if earlier versions of 25.x are affected.
The bug does not appear in Illustrator 2020 v.24.3.0.
Some connection with GPU rendering and graphics card does not seem to be ruled out.
If I turn off GPU performance in Illustrator version 25.4.0, then switch to path view on an illustration with the grid on, the switch takes longer than usual, but Illustrator doesn't hang, and I can also switch back to preview view.
