Short description of error
Issues with the new "OpenSubdiv" modifier method.

Exact steps for others to reproduce the error
-Add a simple plane mesh in Blender 2.8
-UV unwrap it
-Import a texture and apply it to your plane
-Add a Subsurf modifier

Here is the issue in details.
I was doing some texture work on High-poly models, and when I applied the textures to my model, they were deformed in places.

I later learned that the method used in Subsurface modifiers was changed :

Would there be any way to bring back the old method ?
because this is going to break a LOT of my models.

@Sergey Sharybin (sergey) will other methods like the old one be available in the future?

@Aza (azagwen), can you prepare an example .blend file, that shows the problem, please?

@Jacques Lucke (JacquesLucke) can I directly link the .blend that I used for the screenshots ?

yes, make sure that the textures are packed into the .blend file.

Here is the .blend in question, I just deleted every unnecessary element, only the parts that have the bug are left and the environment.

(tell me if you need anything else)
