Short description of error
Seems like TAA of eevee is not applied when "render viewport animation and image" is used.
The renderings look like it shoot only one sample.

F12 works, but viewport animation is much faster than ctrl + f12, even when sampling was applied some versions ago. And at the moment it's just more stable then rendering eevee over f12.

Note seems to be that via background rendering the taa is not being respected. previously the FSAA would solve this, as we removed the FSAA we need to get TAA back for viewport rendering.

Now it works, but there is small difference:
This is screenshot from viewport. And lines are not aliased due multisampling.

And this is vieport render.

I think, lines should have AA too (from render-settings). What do you think?

Yes, it that is unrelated (non eevee and non Taa) so please open a new ticket for it
