With a room-scale Vive I haven't noticed anything like that.

The game just rolls with whatever velocity you have at the time of letting go, so your controllers would have to be spazzing when you try to jump.

If you always go left and forward regardless of what sensor you are facing, it might just be your form. I would suggest switching hands every once in awhile.

I tend to go more left than I expect, but my arms aren't quite the same length so I assume it's that. I could try to adjust my movement to compensate, but it would be nice to have some kind of "calibration" to allow me to jump directly forward using the same arm motion I use in real life.

I tried again after the recent oculus update and it seems much better now, occasionally got a very slight left bias but completely managable where as before it was very frustrating. Never measured my arms so no idea if that could be part of the issue.
