Detailed description: It’s possible to run in place.
What were you doing at the time? Holding left mouse to run towards the cursor and then letting go. It seems it’s possible to be “stuck” running in place. I’ve only achieved this near a wall, but I don’t believe i was touching it.
How consistently does this happen? It’s difficult, if not random, to reproduce. However, I’ve been able to do it intentionally a few times.
