Closing inactive Tabs

Aggressive background tab hibernation

Hello, I am using multiple browser windows with a lot of tabs. Since the 3.5 update I have noticed that Vivaldi is closing inactive tabs very aggressively. It only keeps a few tab active. From roughly 10 windows with 100+ tabs in total only around 5-10 seems to be active at any time.
I have noticed this on Arch system with 64GB of RAM and Ubuntu 20.04 with 32GB RAM. I don't think the memory is the problem as in 3.4 was working as expected on the same configurations and use cases.
I know Chrome 87 brought some some power saving features and tab management - can this be the issue?
Any idea how to configure the power saving behaviour? I checked the flags and the settings but nothing seem obviously related.

P.S. Don't criticize my browsing habits - that's why I have a lot of RAM + F2 key

@Gwen-Dragon yes this is what I mean. Even pinned tabs are getting hibernated.
I am seeing similar behaviour in a Windows VM so the issue might not be Linux specific.

I did a bit more digging and I found this guide for Edge: https://www.tenforums.com/tutorials/165231-how-enable-disable-sleeping-tabs-microsoft-edge-chromium.html

But I can not find similar settings neither for Vivaldi nor for google chrome. Any idea how those can be accessed in Vivaldi?
I tried:

vivaldi://flags
vivaldi://settings/system
chrome://settings/system

I think I solved the mistery - the issue seems to have been the profile-sync-daemon I recently start using. After disabling it the tabs remain open as they are supposed.

Background tabs are getting hibernated very aggressively for me, too, since the last update (3.5), and I only ever have one window open with between 3 and 10 tabs. Even pinned tabs are getting hibernated. And I don't have that profile-sync-daemon OP was using.

I don't have any extensions that should do this, and I haven't manually changed any of my flags. (Ubuntu 20.04 for me.)

I've been checking the Vivaldi task manager periodically throughout the day when I think to, but I can never seem to catch it happening. But every so often I'll go to a tab that should already be loaded, and when I get there it starts loading like I'm opening the page for the first time. It's particularly annoying when it's my Discord tab and I have to log back in again (that happened twice yesterday).
