I've seen this issue posted in a few different forums on the web and I recently have been having the same issue, as well as some of my team mates. When turning on "show grid" it slows illustrator to a complete halt. I can barely do anything and it's making my job nearly impossible to do. I have tested changing my view from GPU>CPU and back again to see if it helps with performace to no avail. I have also updated, uninstalled, and re-installed illustrator.
I am on macOS Catalina 10.15.7 (am not able to upgrade due to our work systems) and use the latest version. My coworker started having this issue when he updated from v24 to the newest version and now the old version is unavailable to install.
Please fix this issue. The only replies from Adobe I have been able to find are the standard tech support 101 (unplug, restart, reinstall, update) with replies of "We can't seem to recreate this issue." Well, we promise you, it's real and it's a problem.
Have you tried prodesigntools?
We cannot access that site on our computers or download any programs that havent been requested through our service center. I work at a fortune 500 financial company and our security/firewalls are SUPER tight.
Sorry about the trouble. I would request you to share a few more details like:
We are here to help. We just need more information.
Thanks & Regards,
The issue happens in any document, even a new blank one. I have tested dot and line grid set-ups, and useed CPU/GPU performance. The files are locally saved on my hard drive. I've also seen this issue posted in other places on adobe and in other forums. I'm not sure what is causing it, but it seems to be more than an isolated incident.
Thanks for checking that. I have shared your feedback with the team. Would it be possible for you to share a small video demonstrating the issue? It would be really helpful as I am unable to replicate this on my Mac, and I totally understand the issue you and other users are facing.
Also, I would request you to try the following steps and let me know if it helps:
I will be looking forward to your response.
