Short description of error
The navigation/sculpting becomes unusable slow in sculpt mode when using the material color shading type.
If I switch to other color types like object/attribute/single/random things go back to normal (not to mention that if I switch back to material or texture, it crashes, but that's in another report )
Is this slowdown expected because of the new "PBVH Draw Support for EEVEE" feature?
Exact steps for others to reproduce the error
To replicate you'll need a little bit of polygons. In my case around 1 million and half polys was enough
So open blender
Add a subdivision surface to the cube and set the viewport level to about 9
Apply the modifier
Switch to sculpt mode (you should be in material shading already)
Try to orbit the scene
As you can see, everything is super laggy and impossible to work
Now switch to other color types (object/attribute/single/random) and everything is normal again
