High RAM usage after visiting specific websites

Albi

What happened? How did it happen? What are the steps to replicate the issue.

I'll post here since it's more related to create new thread. As I've written before, I set it up on a new, clean profile. However, a few hours after my post in the previous thread, the memory consumption for the Orion RC process grew to 5+ GB (sometimes spiking to 15 GB), while all tabs and extensions seem to be within normal limits.

I've tried toggling various settings, disabling or enabling site settings, turning off the content blocker, changing the tab display, switching Low Power Mode, and enabling Compatibility Mode for all sites.

I've managed to pinpoint the problem. A sharp increase in RAM usage occurs after I visit my self-hosted Dokploy. Closing the tab and restarting the browser doesn't help. The only solution is to clear the Cache, Local Storage, and other data in "Manage Website Data...", remove it from history(just in case) and browser restart. I just tried to reproduce the issue on the Cloud version of Dokploy, and it happened, even though I don't think I was able to before.
The issue doesn't happen in Safari or on a clean profile (only after some time).

Expected behaviour:

The "Orion RC" parent process to use <1GB of RAM, similar to when using a fresh profile

What version of Orion are you running?

Version 0.99.136.2-rc (WebKit 623.1.8.0.0)

Hi, do you have any publicly-available sites you've seen this occur with?

Albi

RoxyRoxyRoxy I attached a link to Cloud Dokploy. Memory usage goes through the roof even on the login page.

Hmm I can't replicate that on the non-rc version. Are you just seeing this on RC?

Orion non-rc with clean profile:

I just logged into the site, clicked through all the left menu. But I did this yesterday before going to sleep, leaving the browser open. Maybe I need to leave it running in the background for a couple of hours?

This is my Orion RC. With all the extensions I use and ≈70 (suspended) tabs:

Could the reason for this be that their website specifies the favicon as an SVG?

<link rel="icon" href="/icon.svg">

And it's damn huge: https://app.dokploy.com/icon.svg

<svg xmlns="http://www.w3.org/2000/svg" width="6323" height="5778" viewBox="0 0 6323 5778" fill="none">

That's why my browser was a bit lagging when browsing history(via top system bar or address bar), unless I cleared the site data...

I have a theory that when I browse a website, my history gets filled up with this svg favicon. And the amount of memory growth depends on the number of items in the history. I've noticed this issue when accessing the site through history autocomplete while typing in the omnibar, even though the cache and other data for this site have been cleared.

I created this website to fill the browser history with problematic SVGs favicon: https://albatrosicks.github.io/svg-favicon/

I clicked a button(populate tabs with random path) for a few minutes and managed to fill 700MB in a clean profile with one tab:

Looks truthful. I turned off history and "Show favicons inside tabs":

Turned history back on and opened the same tabs:
