High client CPU use in preview mode

Question

Hi,

On some Confluence page, when I'm in preview mode, the CPU usage of my client become high:

The name of the process consuming CPU is Web Content, a process related to Firefox.

This issue also occurs when I'm editing a page during a few minutes.

I'm using Firefox 79.0 on Ubuntu 16.04.7 LTS. I can reproduce this issue using Chromium.

What can I do to troubleshoot this issue?

Thanks.

So time to double check on the another confluence version.

I made a test with an empty page with just a title (so without any macro). The effect on the CPU consumption is less important but the process "Web Content" still uses 30% on every cores.

Hi!

How about the macros on that preview mode ?

Is this related on exact page? or for any pages?
