Q: Grease pencil, how "Anti-aliasing Threshold" works? With: Eevee, 2.8.6, 2.9.0, macOS 10.15.4, Radeon RX 580.
My Temporal Anti-Aliasing is quite bad, it's very anoying.
My TAA is good for meshes through to Film&gt;Filter Size parameter.
If I put &quot;1&quot; to &quot;Anti-aliasing Threshold&quot; it's much better than &quot;0&quot;, but not enough. If I try more than &quot;1&quot;, it doesn't change anything, it doesn't blur the GP, even if I put &quot;1000&quot;.
I've tried to increase Sampling&gt;Render, without success.
In &quot;Hero&quot; by Pepe Land, I can see there is no flickering due to aliasing, so it must be possible.
Here is my file, thanks!

There was a bug with Anti-aliasing  in pre 2.9 versions. Are you up to date?
If you're experience flickering lines when moving the camera or an object then this is a known bug. I believe the fix at the moment is render in double the size and then compress. This works for me but naturally takes significantly longer to render.
Thanks
