Question

Sketch

When scrolling or moving around the board, some kind of curvature occurs and sometimes extra and non-existent objects appear, then a line can or a square with some color, it all disappears immediately but gives discomfort, as if some kind of beta is used and not a full-fledged Sketch, I think you can understand what I mean, not everything goes smoothly and the picture is not displayed immediately correctly, if it doesn’t glitch for a short time

Answer 1
