I can’t reproduce this. Post a screen recording of this happening in the help vault.

It’s actually happened to me:

The issue occurred exactly like @thomasvs described his issue (although I’m running macOS and Obsidian v0.13.10), but…

Weirdly enough, the problem is currently gone after I did this:

  1. Opened the Help vault
  2. Closed all other vaults.
  3. Re-opened the regular vaults.
  4. Closed the Help vault.

I’ll shout if this recurs.

The issue occurs to me although the steady state CPU usage is not as high as @thomasvs (about 20%).

To reproduce this,

  1. open several notes in the preview mode.
  2. reload without saving.
  3. wait to the steady state.

I found a way to lower the high CPU usage:

  1. do the same as above.
  2. toggle the editing mode and toggle the preview mode again.

Then the CPU usage becomes lower from the steady state.

Update obsidian. Please, Post a screen recording of this happening in the help vault.

I updated v0.13.23, and now the problem seems to have been solved.
The CPU usage is no longer so high.
Thank you @WhiteNoise!

I’m reporting this because it seems to be related to this topic.
I’d like to know whether it is a bug or a normal behavior.

When I open files in new panes, functions like t.queueRender are called many times even after I close the panes.
Here are the results on Performance tab in devtools.
