It started to happen yesterday.
Even if I keep pressing the buttons, my character stops walking all by herself. And I have to press them again, she walks and stops again.
It happened with my friend too, and he just pressed alt+tab to fix it.
I tried everything, I even restarted my PC, but nothing worked.
Can anyone help me, please?
I have the same problem. 
Someone know how to fix it?
I have the same issue.
It’s somewhat possible to mitigate it using a joypad, creating this stuttery movement: https://streamable.com/p47p (focus on the sfx and legs’ animation)
Just wondering, but do anyone encounter this problem where your clicks are not properly registered as well?
As in, even if you click a button, it doesn’t seem to acknowledge it and you have to click again.
It feels like it could be related.
The problem is also only happens somewhat randomly rather than consistently.
There was once I was having smooth performance for maybe half an hour before I got stuck in that state, so this may be due to the netcode as well.
The switch happened when I was just running through a map rather than after changing a map, so I have no idea what triggers it.
