Question

GPU shape preview confusion?

I have loads of apparent errors in Illustrator.

My shapes never align to where they're supposed to. Ref screenshot, that's a solid shape but there's a descrrepency between the line and the fill.

This goes away if I change to "view on CPU", but illustrator isn't workable in this mode.

I have a pretty robust Apple Silicon M2 Max Mac, so am confused what's happening.

Is my shape wrong, do Ii need to redraw it, or is my illustrator wrong?

Thanks for the support. Is this an issue with Apple silicon?

I don't think so, GPU Preview had these kind of artefacts since its introduction, it is not perfect, but it has improved a lot.

GPU preview is fast, but not always accurate., especially when you zoom in a lot.

If I don't trust what I see, I temporarely switch to CPU Preview with Cmd E.
