Start Draw in a current daily. Go to Tools > Options > Draw > Grid. Enable "when rotating" in section "Constrain Objects" and enter 0.3° into the field. OK. Draw a flat, long rectangle and bring it in rotate mode. Rotate the rectangle. Notice the rotation angles are restricted to 30° steps. Go to field "When rotating" and enter 30°. OK. Try to rotate the rectangle. Notice, that rotation is not possible. This too is likely introduced by the Degree100 work, see bug 139379. It might have a different place in code.

It is not fixed. If you enter an angle into the field in Options and click "Apply" the angle value is divided by 10. If you do not click "Apply" but click "OK" and reopen the dialog, the value is divided by 10 too. Draw uses the value, which is shown in the field, when click "OK". The same error is with the point reduction angle.
