The mirrors on my 2017 F-3 Limited were poorly designed and vibrated like crazy at highway speed. (More crap from Can-Am Engineering...don't get me started.) I found a simple, effective solution. I took an inch and a half piece of black hose, cut a couple 1/4" wide, longitudinal slices from it, and wedged them into the gaps where the mirror housing joins the frame. These rubber wedges press in easily, don't stress the hard plastic parts, take out all the jiggle, and stay put. Mine haven't shifted in 600 miles, and both mirrors are now rock solid. The attached picture shows where to place them between the housing and the frame. The hose material I used is reflected in the mirror. This was a huge improvement, cheap and invisible.
Yeah, a couple of others have been bothered by the same problem, Jambo. You can also wedge something in the gap at the top of the mirrors, or take the mirror off and put some tape on the F3 body and put the mirrors back on. This works very well too.

It blows my mind that the F3 and F3-S don't have this problem (mine on my F3-S are rock solid with no vibs etc) and yet the Limited and T models are having these issues. Yes, I understand they are different designs but WTH!
My first thought when I bought the F3-S and rode it was, HOLY CRAP, great mirrors finally! Almost every street bike I have ever owned has had crappy mirrors that either buzzed or gave poor rearward view.....
