Vivaldi frequently crashing, probably out of memory

Sebastian69

5.4.2753.37, also being problem on earlier versions
Arch linux | ZFS | systemd | XFCE | ASUS S435 | Intel CPU | Intel TigerLake-LP GT2 | 16 GB RAM
happens multiple times a day (laptop is shut down every night)
happens typically when more demanding tabs are open - google drive, slack, and such
only about 15 tabs total are open at the same time, divided in 2-3 separate windows
not more than 7GB of RAM seem to be used afterwards (there should be plenty of capacity left)
extensions in use: Lastpass, 1pass (deactivated), uBlock origin, Vimium

Am I alone affected? Any ideas how to mitigate the issue?

@Sebastian69 You have about 45 tabs (15 in each 3 windows)?
Check in Vivaldi taskmanager Shift Esc which process consumes so much that your kernel terminates Vivaldi with OOM.
Perhaps a webpage or extension running berserk?

It's not easy to be looking into the task manager right before crash happens. Is there any way how to dump memory usage logging into some file?

However, I don't see anything crazy going on there, for now. I've also added the list of used extensions.

Well, I have been using Vivaldi today without Figma running along, and I have a theory, that Figma renderer causes peak in memory usage, which crashes Vivaldi.

I will learn about cgroups soon and try to limit Figma processses, so when RAM is gone, Figma gonna crash, not my main browser.
