No other input devices connected. I was getting it in Firefox and Chromium but reset cache in Chromium and it works in that. Seems very difficult to track down. At least I can give actual feedback now :).

Interesting. I am lerping the camera movement, specifically using a spherical lerp. I tend to mostly test in Firefox so this is interesting. But I run a Linux Machine. Linux Mint and use Firefox. I also do test in Chrome. What operating system are you using? It is really weird that you have this issue in Firefox but not Chrome, I am not sure what to think of that. Thank you for trying it again.
