**Versions 5.6 and earlier:**  
During Edit Mode, the mesh turns whitish. However, upon validating the modification, the mesh returns to its intended original color.

**Version 5.7:**  
The mesh turns whitish, but when the modification is validated, the whitish vertex colors are permanently saved to the mesh. This can only be reverted by using **Edit → Undo** (specifically for the bone manipulation). Simply entering “Bone Manipulation” mode without making any changes triggers this bug.

It appears that a simple visualization mode is becoming embedded/baked into the mesh vertex colors.

**Current Workaround:**  
The only solution I have found is to perform all bone manipulations in version 5.6 and then export the file to version 5.7.
