Canvas is laggy with larger number of nodes

Bug reports

I have a Canvas of ~140 nodes and similar number of edges.

When I drag or zoom it gets laggy, particularly once zoomed in so that text is rendered.

The lag is more pronounced when the window is full-size on my larger monitor (3440 x 1440). It’s still present when full size on the laptop’s monitor (1728 x 1117)

:white_check_mark: Reproduced in the Sandbox vault.

FWIW I found this similar post.

Steps to reproduce

  1. Start sandbox vault
  2. Open it in finder
  3. Add test.canvas
  4. Open test.canvas in Obsidian
  5. Zoom out so that the text is not rendered. Now zoom in once.
  6. Observe the lag when :
    • zooming in and out
    • Dragging the canvas around

It happens on Windows, too, so I bet this is either a limitation of Electron, the engine behind Obsidian (if Obsidian were to be written in a native programming language, things would probably run butter-smooth), or the graphics framework that Obsidian uses might be far from perfect.
