Summary0000973: Wrong outline in pocket
The enclosed part contains a pocket that comes from Sketch001. However, the view of the pocket on the screen does not match the dimensions of the sketch. The radii of the two fillet-like corners in the +x direction are shown much too large compared to the sketch itself. If you open the sketch, the right curves are shown.

No, it isn't the granularity of the curve's rendered segments. It is the radius of the curve. Referring to Sketch_Of_Pocket.png, The outline of the resulting pocket is visible in black, the outline of the sketch itself in green. Note that the radius of the lines in the sketch has been set to 1.0. However, the shown radius in the pocket is closer to 2.0 or 3.0.

I suspect that this is a caching bug of some sort. The shown radius in the pocket represents an earlier state in the sketch as it was being constrained. The order of operations was:

Create sketch
Constrain sketch
Create pocket

Your slot profile is not closed. Reference geometry (magenta) and construction elements (blue) are discarded by Part Design features. Close your profile and the pocket updates correctly.

I'm surprised the pocket didn't fail completely, that's what the bug is IMO. It should warn the user that the feature cannot succeed because the profile is not closed.

This bug is fixed because from the sketch we try to get a face which fails in this case now. So, FreeCAD won't let the user create a pad/pocket.
