A straight finish is appearing in some sharp corners

[rubensscarelli]

I've been noticing for some time that in some sharp corners a straight finish is appearing. This is just visual, but it's very annoying. Apparently this is happening only in Illustrator installed on macOS. Anyone else with this problem?

Yep, it's happened to me for years... don't know of a fix lol. But it only happens when you're zoomed in super far, so making the illustration bigger will help I believe.

Try using CPU preview. This seems to be a problem generated by the "over-active" GPU preview. It is only screen problem and does not print.

Oh wow!! Had no idea, thanks for educating me lol!

Ruben, Brady,

In addition to what Larry said, you can toggle between GPU and CPU with Ctrl/Cmd+E.

And you probably know this:

GPU is faster, sometimes too fast, so it gets ahead of itself.

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 (job description Adobe Illustrator, and she is always eager to help) sometimes moves in mysterious ways).

Here are a few more pages about GPU troubleshooting:
