How can I show the Search Area box on a tracking point? This has never been an issue until just now but consulting the official documentation it appears that there should be a search box which is distinct from the pattern area.

Only... I don't seem to have it. I can see, rotate, deform etc. the pattern and I can resize the search area but there's no box to see the defined search area.

I've got some fairly fiddly tracking to do and to save time, I figured there's no point having huge search areas around each pattern, but the patterns are varied and organic in nature...

Maybe I've missed something but none of the videos I've caught seem to have it either. Did they removed this or is it disabled somewhere?
The visualization of the search area can be enabled in the Clip Display panel in the section Marker Display. Enable the checkbox named Search to show the search area. Alternatively you can also select a tracker and press Alt+S.



The properties for the search area can be found in the Track tab on the Marker panel.
