Hey, this has happened to me several times in the past! I thought I was just going crazy. Mine didn't switch between slant and straight views though, mine just stayed slanted. What I remember about it - did not go away when crouching or proning. I think it happened on bootybay, as well, though I can't say entirely for sure.
Huh. wow. The only thing I could possibly imagine is that you had an Oculus Rift or a similar, Steam-supported VR kit connected; the Source 2013 SDK has native support for Oculus Rift (although we didn't take it into account for vehicles).
I had that happen to me once before as well. I think it was also in the com vehicle. And it was WAAAY before Source even started to incorporate VR.
Its a source glitch,it appeared to me 2 times in a specific period of a server named GMTower in GMod. Said period was end of lobby 1.
I've had it happen in Gmod and Empires before as well. Can't remember the circumstances but it is a source bug.
That was happening quite a lot some time ago to me. It seemed to be caused by a lag. Also sometimes happened while spectating somebody. Very similar like when admin drugs you.
Well at least your view isn't getting locked every 1/12 times to the underside of the CV front right when you get into drive mode.
