I am trying to use TAA where the camera viewport is smaller than the window, but it seems to distort the aspect ratio of the view as well as as add a black band (see video). When zooming in and out, the TAA samples shimmer like they're not correctly aligned with the image being rendered.
Everything seems fine when the viewport rect is the whole window. Is there some additional setup I need to do?

Yeah TAA doesn't respect the viewport.
It's a known bug, there are open issues on github.
It's a little tricky to fix

Cheers, do you know how to find one of the issues? Sorry, I did try, my github issue search fu wasn't strong enough!

I'm not seeing a simple "TAA dosen't work with viewports" issue, but it's generally a known issue yeah

Thanks! I also found this one with general follow up work, but also doesn't mention viewports -- https://github.com/bevyengine/bevy/issues/8423 -- it does mention a lot of other stuff
