Short description of error
After using box hide tool and doing Undo + Redo, it creates visible artifacts...
Exact steps for others to reproduce the error
Box Hide Undo Redo Bug.mp4
I get that issue in both of my machines. And I also checked by exporting and importing as an OBJ but always get the same case.
Here's the exact file.

@Pasang Is that video you uploaded playing in your browser? Here on Linux in Chromium and Firefox it is not playable.
@ronsn It should play in Chrome. But it sometimes doesn't play in Edge. Can you try downloading the video?

I can confirm, looks like this here:
@Pasang Downloading the video worked. I can confirm the issue too, but I couldn't reproduce it on other meshes with much higher poly count. Is this the only mesh, where that issue occurred?
Looks like art somehow
@ronsn Curiously yes. It doesn't happen in any other meshes. Maybe something's wrong with it's mesh data. I tried with OBJ and FBX export-import but same issue.
@Pasang The Issue does not occur in Blender 2.79 but in Blender 2.80, so somewhere in between those versions there must be the commit which is responsible for that issue. Bad news is, I cannot compile Blender 2.79 on this machine to find the exact commit.
What kind of worked was to remesh the frog and maybe that might be a solution for you for now.

After investigating, the bug is not related to that particular mesh, It can also be reproduced by subdividing any other mesh to a point it creates multiple nodes and setting it to smooth shading.
If this is not fixed before, we may revisit this again after reviewing the design and merging the new visibility system in D6070, because that could also fix this issue.
