I previously posted this bug but it was closed as nofix. I disagree with the feedback:
I tested the same page in Firefox, Safari and Chrome, and I do not experience the same behavior. In Orion, if I have a tab open with this website, the CPU will be pegged at 100% even if it's not in focus. In other browsers, I only experience high CPU (and not 100% even) if the tab is active. If not, there is very low CPU usage.
Therefore, this seems to be a bug only in Orion (and not Safari).
Steps to reproduce:
An example site is: https://www.cloudways.com/en/
I tried with a clean Orion profile and it does the same thing.
Expected behavior:
Not to peg the CPU at 100% while the tab is open.
Orion version: 0.99.125-beta
OS version: Ventura 13.3.1
Hardware: M1 MacBook Pro 14"
