GPU Grayed Out
Importing an image into a brand new illustrator document and embedding the image disables the GPU acceleration.
i.e. using the crop function disables the GPU.
I suspect there may be other ways the bug manifests itself, but the above process is the only one I can confirm.
Problem has persisted over many of the last few versions of Illustrator, I beleive for years.
It is critical that Adobe take this seriously.
Some large files we have received form our customers cannot be opened without this bug taking effect.
CPU preview is ridiculously slow, and not a valid workaround.
I have used Macs and Illustrator for 20 years, and have never seen an app with such abysmal performance as Illustrator with CPU preview.
