These you can see very often nowadays.
Scope bug, while playing and spectating.
No running animation on some bodies, just still 3D model moving.
Thank you for pointing those issues out, they will be passed on to our dedicated teams so they can have a look at it.
Have a great day!
@raibi updated post with video.
Also asked my friend, they confirmed that they experienced the same bug. But when we play together we do not see the bug on the same character, so problem is local.
Scope issue I get this regularly with the 7x scope
