System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2060 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 517.48

Blender Version
Broken: version: 3.0.0 and later
Worked: 2.93

Short description of error
That mesh I put in .blend file is from my old project (started in 2.79). For some reason normals on that mesh go crazy if I try to edit it in Face selection mode. I found that this particular mesh can't have shapekeys and auto smooth enabled at the same time.

Exact steps for others to reproduce the error

Add Basis shapekey to the mesh
Enter Edit Mode
Select Face Selection Mode
Move any face

Hi, thanks for the report. I can confirm this locally. Happens only when center toggle for mesh element is checked in viewport overlays panel.
Will check when exactly this was changed, though I'm not sure how much bisecting would help.

@PratikPB2123 It should be noted that this only happens when Apply Shape Keys In Edit Mode is enabled in the shape keys panel. And this seems to be fixed in latest master.

Right.

this seems to be fixed in latest master.

I can still repro in latest master.
