Sounds very doubtful.

[self controlView] is probably unreliable in your cell - you might want to 
check it. But even if it’s correct (being the NSMatrix for the browser column) 
invalidating the whole thing is going to be very sub-performant (though should 
work).

Note that NSBrowser, unlike a NSTableView, allocates one cell per row within a 
NSMatrix - it does not reuse and redisplay a single cell.
