Rotating an object with 3D Extrude & Bevel causes pixelation in v29.8.2
I don't know if any user has raised this before, but the 3D Extrude and Bevel in Illustrator (29.8.2) has an issue. When trying to manipulate an object by rotating it, the object completely pixelates as it is adjusted. It's impossible to ascertain the positioning as it just becomes a massed blob of pixels whilst I am trying to position it. Whether positioning it manually, or by using the X,Y, Z sliders, the problem still persists. Zooming in doesn't work either (the pixellation just increases in size). See screen grab- as you can see, the item I am trying to manipulate is completely pixelated as and whenever I try to reposition it.
The Classic version doesn't have this issue, and the object remains clear at all times. A shame as the new version has more features, but it's quite unusable because of this.
Can you sort this issue out?
