Worked: (newest version of Blender that worked as expected)

Short description of error
I tried with Eevee i don't have the problem only with cycles.
Is only when i render animation or image. I can't see this glitch on viewport.
I tried with blender version on mac and window and multiples different graphics card but the problem is still append.
With or without modifiers or movement of camera still in.

Exact steps for others to reproduce the error

Open blender with love.
Make a beautiful animation with shape keys.
Turn on motion blur.
Problem when i render :(
Close blender but with love to help. :D

Thanks you

Glitch shape key motion blur .blend

Hello,

I found what is my problem.
I will explains my process

I add a surface, edite mode, delete 3 point on it to get 1 vertex.
I extrude my vertex to be a line (simple line, (exemple = 3 extrude of vertex on z axise ) )
I add a modifier skin and Subdivision.
Add a movement = position, 1 et 2 with shape key and make some animation on my time line.
In render setting turn on motion blur and render

Until here no problems

I try again with exactly the same setup, except when i extrude a vertex with multiple direction like a real tree then animate after with shape keys.
When i render after this step i have a glitch.

I hop i was clear to explain.
Sorry my english is not so good.
Thank you

@pacpac I am looking at older reports, is this still an issue? Or have anything changed?
