Additional information

Actually I’m a plugin developer and was looking to improve performance on canvases with a lot of images. This is how I’ve stumbled across a bug in Obsidian code that was ruining the performance. Upon deeper investigation I’ve discovered another issue. So, there’s actually 2 issues.

I’ve made a plugin that resolves both of them GitHub - Qbject/obsidian-canvas-performance-patch: Fix issues with canvas performance.. I’m not going to submit it to the plugin library, it’s more of a demo to make it easier for developers to fix the issues. The readme file contains more technical information. I hope it helps.

Hi, thanks for the new version!

Though it looks like only the css backface-visibility issue is resolved. But the file nodes still unmount and mount back on every frame while panning.

Should I post a new thread, or this one can stay around?
