You are right - they have fixed the "rotate while zoomed in a sketch" (SPR#350038) which I identified, but appear to now have an issue with viewing the origin when sketching. This seemed to be a new fault, but I found that it is fixable - go to "view" and switch on "origins". Then right click on the origin and "hide" it. The blue origin then disappears in normal viewing, but appears in red in a sketch.
