I was able to reproduce this issue on my machine Ubuntu 18x64 and Win 10x64 with Nightly 83.0a1(2020-10-18) (64-bit) but is reproducible on chrome too.

Not a WebRender bug.
Creating ui.systemUsesDarkTheme = 1 on about:config allows to set dark theme by default (bug 1641421).
I see the same behavior with Chrome Dev on Gnome XWayland, Debian Testing:
$ google-chrome-unstable --force-dark-mode https://www.youtube.com
White for a tiny moment, then dark.
If there is something that could be improved, it would likely be done as part of bug 1641179, I assume.

Its strange vivaldi behaves different to chrome. Does the same white flash happen in chrome when youtube.com is explicitly set to dark theme rather than system default?

Conditions:
System: (apparently) a light theme.
YouTube: manually set to dark in the top-right 3 dot menu.
Chrome Dev test:
Yes, YouTube is white for a tiny fraction of a second before turning dark. The flash does not occur when pressing F5 or Ctrl F5, but when loading additional YouTube tabs.
Well, I guess it would be an enhancement then. Not much of big deal and can be solved by using dark reader, but irritating nonetheless. I still wonder what vivaldi does different
I don't what changed, but it is fixed in nightly 84.0a1 (2020-10-31)
