Nope. But I just found out something.
It seems like when I turn my HW acceleration on [EDIT: I wrote here “off” before by mistake] (brave://settings/system) then I am not able to reproduce the issue. Or I was lucky. I keep my HW acceleration off because of other bug I tackled here: Megathread: For users seeing high CPU spikes/usage
So again: it seems like the issue is present only when HW acceleration is disabled.
And if it helps here are some of my OS and PC specs:
