GPU Performance stops working when enabled
Illustrator 21.1.0 (64-bit)
GPU Performance shuts off whenever I open a file. I have to close the file, turn off GPU Performance (yes, turn it OFF in preferences), then turn it ON again, then reopen my file to get it working again. I've been complaining about this for months, and Adobe has ignored my complaints. All updates including drivers have been installed and I've completely removed and reinstalled Illustrator.
