Blender viewport not updating while rendering

I am sure this has been answered but I couldn’t find the reason why Blender seems to not update viewport changes. It works just if you move an object and you press G again or enter edit then it suddenly updates the object position. Undo doesn’t even work.

To better understand you problem, please answer these questions or check out these settings:

  • Is the model rigged with armatures?
  • Are there shape keys?
  • Is the 3D Viewport in Solid or Rendered Mode?
  • Do you have any modifiers on your model?
  • Do you have any animation keyframes for the model?

If all else fails, please attach the .blend file in a reply or the main thread.
