Short description of error
Strange surface artifacts appears if you use GPU subdivision + normal map + Armature Modifier. I'll noticed that problem in a project, so I did a example file to show the bug... but maybe I'am doing something wrong...

Exact steps for others to reproduce the error
Mesh + add Armature Modifier + add Subdivision Modifier + add Normal Map to the Shader + activate GPU subdivision

GPU subdivision ON

GPU subdivision OFF
