System Information
Operating system: Windows 10
Graphics card: NVidia Geforce 940mx

Blender Version
Broken: blender-2.80.0-git.26d5a3625ed-windows64
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional)

Short description of error
With Multires modifier in sculpt mode, the object only shows as flat shaded and the "auto depth" navigation function doesn't seem to work, so when you rotate the view it doesn't pivot from the point on the surface you click, but rather from the middle of the object.

Exact steps for others to reproduce the error
Create an object - add multires modifier - add at least one subdivision - be sure object is shaded smooth - enter sculpt mode - rotate the view (auto depth must be enabled in settings) - compare to the rotation outside sculpt mode.

It is a small thing. If this is not regarded as a bug, just let me know. I want to help as much as possible in the evolution of Blender 2.8 Beta

I have a feeling that my bug is similar to this one. I'm on an Intel i3 2 core/ 4 thread, and have a GTX 750ti with the latest Nvidia drivers on Windows 10 64 bit. If I do the same procedure above, with just one multires level, the model disappears completely when rotating in sculpt mode.

with just one multires level, the model disappears completely when rotating in sculpt mode.

(Linux, git blender2.8 tip) It depends on the option "Number of subdivisions in sculpt mode".
For >1, it shows only one division during the view-port movement. The automatic depth positioning for the center point works only when sculpting the 'visible' subdiv #1 mesh points.

This one is kind of random to assign, issues could be in different parts of the code. @Sergey, feel free to reassign.

The smooth shading is more for @fclem, AFAIR he did majority of the new code.

Rotation depth i am not sure what's going on, @fclem, after fixing the smooth shading, feel free to re-assign back to me.

For >1, it shows only one division during the view-port movement.

This is caused of the fast navigate option in the toolbar. This is not a bug.

@Sergey In GPU_pbvh_grid_buffers_update(), grid_flag_mats is currently NULL and leads to a Null pointer dereferencing. So I think it is not comming from the drawing code.

@fclem:At least here, multires objects in Sculpt Mode are always drawn as flat shaded objects, regardless of Fast Navigate being on.

@fclem, ah, if it's matter of filling in a flags array it should be a simple task :)

Shading is now fixed. The auto-depth i can't really see a difference between object and sculpt mode. Is it still an issue?

Hi Sergey Sharybin, smooth shading is working in multires modifier now but I have some new artifacts when I zoom/rotate and the mesh changes to lowres. I'm using hash: 779860d34e

Watch here the behavior. ]]
