Illustrator 100% CPU

Hi everyone, I have a 2014 iMac and after the last illustrator update is very slow and fan keeps switching on. On the activity monitor something called Adobe Illustrator Web Content takes 100% CPU! I installed and reinstalled the app, removed and reset preferences, nothing works. Does anyone know what Illustrator Web Content is and why it takes 100% of CPU? Can it be disabled or deleted?

Thanks!

Hi @Phil Vas your issue could be your GPU is outdated so the application could be relying completely on CPU to render graphics.

On the "high-end" 2014 iMacs came with a Radeon R9 M295X GPU which clocks in at 750 ops/sec.

Current recommended minimums are 2,000 ops/sec.

You can try resolving the CPU usage with the suggestions on this page:

But there comes a point with a 9 year old machine that you have to make a hard choi

Solved the problem by uninstalling the latest version and installing  previous version. Now it works fine!

I do experience the same problem. Adobe Illustrator Web Content running wild with no files open. Can kill the process with no impact on my work at all, but super annoying to always have to open the activity monitor to quiet the fans going wild.

MacOS 10.15.7
Macbook Pro 2017 / Radeon Pro 560 4 GB

And I find it troubling, that keving stohlmeyer is telling everyone that this is NOT a bug, should be more careful in his wording, while being an “expert”. It is clearly a bug, because the software can be installed, no warnings are displayed reagarding gpu performance and every single option connected to this is available. So please uncheck the “correct” answers as such, they are misleading, it's a bug!

And hey Adobe, why do I have to register on a third plattform to push bug-fixing solutions? Get a grip!
