Using ProBuilder 3.0.6 in Unity 2018.0.1.f2. Overall performance of ProBuilder is very very slow. Is this normal? Are performance improvements coming down the road? Some issues I've experienced when editing verts, edges, faces of a model include: Zooming Stalling 1. Move some verts. 2. Alt + Right Mouse Button Drag to Zoom 3. Zoom doesn't work, the zoom just stalls for like 2 secs. 4. Zoom finally works after trying to zoom again. Tool Switching Stalling 1. Move some verts. 2. Press R to switch to Scale. 3. Tool doesn't switch, stalls for like 2-3 secs. 4. Tool finally switches to Scale. Undo Long Stalls Overall Undo seems super busted. Hitting Ctrl+Z to under moving a vert can cause several second pauses.
