Obs-browser-page taking high CPU despite deactivation

[Héraès]

Hello,

I have a 25% of my Quad-Core Q9550 taken by "obs-browser-page" processes (6 ones in total).
I've followed advices and checked "Deactivate when not showing", but in vain.
I've also directly hidden the sources, with no more success : I'm forced to quit and relaunch OBS to make the processes to drop to 0%, but as soon as I reactivate one, it rises to 25%.

What the heck ?

Is the behaviour consistent for all 5 browser sources? What site(s) are they pointed to?

Sorry, France here (3:00AM)
I've just made some test. The most unbelievable is that these processes even launch when I'm in a different scenes collections without any browser source : I've restarted OBS after chosing a collection with just the strict necessary, and 4 of them are still there (with 0% CPU usage, but still).

When I chose back the collection with full scenes, as soon as I unhide a web browser source, it simply adds one more obs-broswer-page process. So unhidding 2 (ex : alerts and text-to-speech), makes a total of 7 processes, with ~0.4 to 1.1% of CPU usage on 2 or 3 processes.

Opening the chatbox (streamlabs widget) close two of the processes, and opens one and send 0.4% to 5% of CPU usage on various processes (always changing). Same for Spin Wheel.

The browser source that demands the most is a public webcam : 8 to 12%.

But the thing is I had the 25% problem yesterday when trying OBS with all of those sources OFF, so what the heck is going on ? Now I have them enabled and it doesn't take 25%.

-----------------

I noticed that when changing to a scene without any web browser source, or changing back to a scene having some, there's creation and deletion of obs-browser-page processes !

There could be a variety of reasons. Do you have any browser docks, as they would also be counted (View -> Docks).

Additionally, while you should have 1 obs-browser-page per browser source/browser dock, there is at least 1 more to manage the others & perform rendering. It should have pretty low CPU usage though.

I have two docks yeah, but that doesn't explain the high CPU usage.
