What i tested happned 5 months ago. if the issue exist 1 month ago too it is the same problem.

The problem lies with the whole thing is XML and SVG unlike Figma's Canvas/WebASM . The whole thing is unable to scale.

They are actually working on a new canvas-based rendering engine in order to get away from using the DOM so that should help performance quite a bit.
