Why is my donut not smooth and sculpting it causes distortion? Im completely new to blender and ive been following this tutorial: https://www.youtube.com/watch?v=6OTX3ZdYvEA&amp;list=PLjEaoINr3zgEq0u2MzVgAaHEBt--xLB6U&amp;t=0s

I started noticing around part 4, that my icing looks edgy and jagged especially when zooming in. At part 5 it got even worse when i started sculpting and those lines appeared.



Have i missed something or is it related to blender settings or gpu/cpu?
I think i figured it out. I made a copy of everything and did not hide it from the view which caused the distortion
