Illustrator CC2020 multiple project tabs feature quits working randomly on macOS Catalina

[Dean Rank]

I typically have 4-5 projects open at a time in tabs.  Randomly about every hour or so, Illustrator will lose use of this feature and I will only be able to view the project that I was viewing at the time.   Clicking on other tabs does nothing.  Only restarting Illustrator or dragging the tabs into their own windows rectifies the issue.  This is my second post because it's super frustrating.

I have tried:  Uninstalling/Reinstalling, deleting preferences.

Illustrator 24.0.3

Mac OS Catalina 10.15.2

iMac 4.2 ghz , 48g RAM, Radeon Pro 580 8 GB

Hi Dean,

Thanks for reaching out. I'd recommend turning off the GPU Performance under Preferences > Performance.
Let us know if it helps you out.

Hello Ashutosh,

This setting did help my tabs problem however my performance without the GPU took a major hit.  Will this be fixed in future updates?

Thank you,

Dean

So sorry to hear about this. We are currently investigating this issue. I would request if you an share a few more details like:

1. Screenshot of video of the the process.
2. Screenshot of display settings (System Preferences> Displays).
   
3. SPX file for system information.
   > Go to Apple Menu
   > About this Mac
   > System Report
   > Click Save in top menu
   > Save the SPX file with your name to Creative Cloud
   > Share the download link.
