Adobe. Make It an Experience.Chris Slowik commented
Latest version of illustrator and I still cannot open more than one document with GPU Performance turned on. If I turn it off, there are ZERO visual updates on the canvas, no matter what I do (pan/zoom, move things etc), until I turn GPU performance back on.
My Illustrator workflow is so painful. Please fix.
Sorry to hear that you are facing this issue. We have fixed similar issue in 23.0.3,
Can you please upgrade to 23.0.3 and let us know if your problem is resolved or not?Chris Slowik commented
I also experience this home screen display frequently when I open files from Finder and Illustrator is not open yet. Need to close the file and reopen to get it to display.
This issue has been fixed in latest release. Please upgrade to 23.0.3 to get the fix.
