System Information
Operating system: Linux-5.3.0-26-generic-x86_64-with-debian-buster-sid 64 Bits (Ubuntu 19.04 and 19.10)
Graphics card: GeForce RTX 2080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 435.21

Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-12-04 11:32, hash: f1aa4d18d4
Worked: 2.80

Short description of error
Rigged character is linked to a scene, then Object/Relations/Make Proxy is used to make proxy armature. When the character is animated using the proxy armature, the animation looks fine when run in the viewport, but when rendered (either in Cycles or Eevee), there are random glitches in single frames (different each time you render) where the character is suddenly in another position -- often far away from where it should be and strangely twisted.

I have to work around the problem by rendering the faulty frames again as separate png files -- which works because the glitch hits different frames each time you render.

If I open the same file in 2.80 it works fine. If the animation is already in the linked object and no proxy armature is used, it works fine.

Exact steps for others to reproduce the error
Sorry, but this issue is very random and I have not been able to produce a test file to reproduce it. It is possible that it only happens when there are several rigged/animated objects in the scene, but I am not sure.

Please attach a blend file with minimal steps to redo the error.

I am sorry, I just can't make a Blend file to show the problem. I have tried. And I just don't have time to try to figure that out. It appears in a larger project that I have, with several linked characters in scenes, that are just too big to upload here. So this is all I can contribute, and if that is not enough then I am sorry.
