Description

I carefully looked at other similar bugs (like #9412), but considering this one only showed up in 1.1.1 (in this specific way) I'm not sure if it's related or not.
This looks to me like the result of a feedback loop in the physics.
These two craft reliably reproduce the problem right on the launchpad. Although this does happen in flight with other craft as well.
I am using Linux But I saw windows users on twitch today having the same problem... So I checked both.

I've been looking more, and this may be the same as #9583 . But these craft do show the problem without even launching.

It is the same issue as #9412 which is itself a very very old issue going back to early versions of KSP.

Try 6 I-beams (symmetry or not) on an I-beam on a pod (any type).

Unfortunately this appears to be a PhysX bug.

Craft attached for the lazy.
