The bug is present on both AMD and Nvidia hardware as soon as async motion smoothing is enabled.
The issue becomes apparent below 60 fps.

Improperly hallucinated frames are visible flickering both in the direction of movement as well as trailing behind, alternating seemingly at random.

  • Distribution: [Gentoo]
  • SteamVR version: [E.g. 1.20.2]
  • Steam client version: [Sep 17, 2021]

  • Gist for SteamVR System Information: [See instructions]

Video is poor quality phone within HMD but gets the point across, use the comma and period to navigate frame by frame, you can see the rapid jittering motion of the hallucinated frames.
