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.
