TV going trough wall and moving track bug

So when i stand onto those moving tracks in this chapter Residue processing the moving tracks go faster than me.
when i look down i can see the texture moving faster.
Also in chapter “Questionable ethics” if i hold LMB onto those TVs on the wall and start hitting them with crowbar they go trough the wall.
Also game freezes after going to windows(ALT + TAB or windows button)
