Short description of error
Scripting Layout. When you drag-open the Tool Shelf in 3D View, then the content shows with maximum scale factor
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Open Blender, Switch to scripting layout. Don't use T to open the Tool Shelf. But open the tool shelf in the 3D View by dragging the plus sign out. The content of the tool shelf will be displayed in maximum scale factor.
Seems that something gots corrupt over the years. Fix is easy. Delete the 3D view editor, and readd it. New created 3d view works as expected then.
