Hmmm. That wired. I did visit the website (in Safari, Chrome, and Orion) and Orion is the only one that's a hiccup. Everyone else fully load the webpage and rubberbans it.

I could possibly guess it's an WebKit or an browser issue, but I'm not fully sure.

      Steps to reproduce:

      1. Open Orion.
      2. Open Acticity Monitor, switch to all processes CPU usage view.
      3. WindowServer's CPU usage stays at 3040% and doesn't drop until I quit Orion.
        This doesn't happens everytime, but usually occurs after I keep Orion open for more than 24 hours, or after macOS wakes up.
        Resetting Orion doesn't help.

      Expected behavior:
      Without Orion running, WindowServer's CPU usage is below 10%, even with Safari & Chrome & multiple electron apps running.

      Orion, OS version; hardware type:
      Orion: 0.99.122-beta
      OS: macOS Venture 13.0.1 (22A400)
      Hardware: MacBook Pro 16' 2021, Apple M1 Max, 32GB

        xiao99xiao Can not reproduce. Please provide steps to reproduce (with video desireably) with clean Orion install.

              <include steps to reproduce the bug; Did you try using Compatibility mode (https://help.kagi.com/orion/support-and-community/troubleshooting-webpage-issues.html)? Did you try using a clean Orion Profile? If applicable, does Safari behave in the same way?>

                can you please elaborate?

                  JEB Steps to reproduce from a new clean Orion profile please.

                      Are you using any CPU-intensive websites?

                        1. open https://read.readwise.io , click some item with complex content structure
                        2. the tab would get stucked, cpu usage consumes over 100%
                        3. close the tab won't help, have to force quit it using Activity Monitor

                          Can anyone reproduce?

                                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

                                  I visited that page on Orion 0.99.125-rc on a 2013 MacBook Air running the latest Big Sur. With no other applications running and no other tabs on my regular profile, I did see what might be considered excessive CPU usage. However, when I refreshed the page, the usage became normal.

                                  You can see in the CPU LOAD graph at the bottom where the usage drops, that's where I refreshed.

                                  I will compare with Safari 16.6 on this machine and update this post.

                                  Update: I can see the same behaviour on Safari as you can see in the image below.

                                  Where you see the excessive usage and then a drop off is where I refreshed the page.

                                    buttonpusherr NOt able to reproduce. I wonder if there is something else at play.
