I'm encountering a red artboard when I open ALL Illustrator files. I think it may be a GPU issue...as when I turn off GPU Performance under Illustrator prefs, it works fine.
I'm running CC Illustrator 22.1 (latest) on a (bought new) 2017 MacBook Pro 2.8 with16GB RAM, Radeon Pro 555 2GB/Intel HD Graphics 650 1.5GB graphics on High Sierra. Here's a video of me opening a simple business card (1.5MB file)...
Edit: sorry that one is about Premiere, but we had this in the Illustrator forum as well.
Thank you SO much for pointing me in the right direction!
Is it working now, @rvickerman?
Only when I have the GPU Performance off...is this considered a bug?
Please follow Monika's link from above and add your comments there for the engineers to see them and to possibly ask you more questions. Also, be sure to vote at that link.
Yes, it is a bug.
