Summary: Original issue was caused by wring detection of whether SS modifier is being applied for render/viewport. After recent dependency graph commit this was no longer an issue. But it still might have happen conflict between viewport draw and scene_update_for_newframe() invoked from render thread when using external engines like Cycles. Solved by adding viewport lock while scene is being updated and objects being exported to the render engine. Same lock was already used for Blender Internal.
