I found that if a markdown (MD) file is referenced in a canvas, editing the MD file also causes lag. Is this a bug? You can try opening the canvas and then opening the MD file referenced in the canvas in another window. If a markdown file is referenced by cards or other markdown files in the canvas, editing the referenced or displayed markdown file will cause their response speed to be as slow as editing directly in the canvas. So, I think the logic and processing of canvas editing and markdown editing should be different, right?
