I've only ever noticed slight shimmering on hair, but not movement artifacts. Maybe it's less noticeable on high refresh rate monitors - or perhaps I'm blind to them, kind of how a few decades ago, I did not notice frame rates being in the single digits...

This hair shimmering is an issue even at native resolution though, simply due to the subpixel detail common in AAA titles now. The developers of Dragon Age The Veilguard solved the problem by using several rendering passes just for the hair:

This technique involves splitting the hair into two distinct passes, first opaque, and then transparent. To split the hair up, we added an alpha cutoff to the render pass that composites the hair with the world and first renders the hair that is above the cutoff (>=1, opaque), and subsequently the hair that is lower than the cutoff (transparent).

Before these split passes are rendered, we render the depth of the transparent part of the hair. Mostly this is just the ends of the hair strands. This texture will be used as a spatial barrier between transparent pixels that are “under” and “on top” of the strand hair.
