Triangle shaped display glitches in Illustrator on macOS

[graciewadee1]

I zoomed in one day while I was designing and white glitchy triangles spazzed through my work. It's the most rediculous thing ive tried to work with. My wacom tablet is hooked up to a Macbook Pro. I've read about turning off the GPU acceleration, but I do not know how to do that. Any tips?

Gracie,

Ctrl/Cmd+E toggels between GPU and CPU (you can untoggle CPU if it fails to help).

This is what GPU is about:

Or, with this exquisite wording by Monika:

Graphics cards are included in the system requirements:

Apart from an inadequate card, the issue can be caused by lack of driver updating, lack of proper recognition of the card by the computer, and whatnot (including rifts in the space time, moon, weather, and the fact that Illy sometimes moves in mysterious ways).

Hi there,

Sorry to hear about this issue. I would like to know if turning off GPU worked for you, or the issue still persists.
Kindly update the discussion if you still need assistance with it.

Thanks,
Srishti
