1. Open Draw
2. Pick the Arc tool (from the Insert Basic Shapes button in Drawing toolbar)
3. Hold down Shift key and start drawing the arc
4. While still holding Shift, click once with the left mouse button
5. Still holding Shift, click again with the left mouse button
Observed result is that the arc shape jumps to a completely different position in the canvas and the gap flips to the other side of the arc!
This does not happen in 4.3.0
I will bibisect this later.

Yes that it an error. It is already broken in Version: 184.108.40.206.alpha0+

Workaround: Use the circle-arc from the "Legacy Circles and Ovals" toolbar.
It seems to have appeared in 5.0, but I got bogus bibisect results from Linux and Windows.
