3D Effects dithering in Illustrator for MacOS
I'm noticing in Illustrator version 29.3.1 in MacOS Sequoia 15.3.1 a graphics problem and dithering of objects that have a 3D effect applied. Specifically, I'm using the 'Inflate' effect and am seeing objects sometimes as dithered or pixelated and others that are smooth and normal. I can temporarily smooth the dither if I move the object on the screen, but then other objects with the same effect can have dithers. I'm using a MacBook ProM4 with 48GB and also two 4K 32" monitors. If I move the Illustrator window to another screen, the dithering still remains on some objects unless I actually move them around. Not sure what's causing this.

Cristopher, if you isolate this object into a blank file — does it behave the same way?
If yes — can you share this test file?
