Short description of error
Sculpting works inconsistently depending on which shading mode you're in and whether the object has active modifiers and / or dynamic topology turned on.

In solid mode sculpting works almost as expected but setting the colour mode to "texture" doesn't work while sculpting and the active object renders as if "single" were selected.

In lookdev and rendered modes textures display correctly but sculpting does not update in the viewport if the object you are working on has no modifiers active and dynamic topology is turned off. The active object IS deformed but you must either leave sculpt mode or switch to solid view for the geometry to reflect this. Otherwise it simply appears that no sculpting has occurred.

Exact steps for others to reproduce the error

Start a new Blender file and switch to the Eevee renderer.
Switch the 3D viewport view mode to lookdev or rendered.
Select the default cube and enter sculpt mode.
Tap G to change the brush to Grab. Attempt to pull its corners around. It should appear that your efforts aren't working.
Switch to solid view. Observe that the alterations made with the sculpt brush are now visible. Change back to lookdev or rendered and they vanish again.
Repeat steps 1 to 4 only this time add an edge split modifier to the cube before entering sculpt mode. Observe how sculpting now DOES show up correctly in lookdev and rendered modes.
Finally, repeat the test in step 6 only turn on dynamic topology instead of adding a modifier. Note the results are identical.

For the solid view / no texture issue, test this by simply opening a Blend file with a model with textures applied, switch to solid view, enable "texture" as the active colour type, then select the textured object and jump into sculpt mode. Note how the textures suddenly vanish.
