Issue was caused by blender internal accessing data from DNA during rendering. There's no simple solution to make stuff thread safe, so for now simply restart rendering on frame update.

|
* Dependency Graph
|
|
* ================
|
|
*
|
|
* The dependency graph tracks relations between various pieces of data in
|
|
* a Blender file, but mainly just those which make up scene data. It is used
|
|
* to determine the set of operations need to ensure that all data has been
|
|
* correctly evaluated in response to changes, based on dependencies and visibility
|
|
* of affected data.
|
|
*
|
|
*
|
|
* Evaluation Engine
|
|
* =================
|
|
*
|
|
* The evaluation takes the operation-nodes the Depsgraph has tagged for updating,
|
|
* and schedules them up for being evaluated/executed such that the all dependency
|
|
* relationship constraints are satisfied.
