Comment (by macca8):

 I have to admit that my immediate reaction to this report was "why would
 you want to click a button for a view that already exists?".
 However, upon investigation, I've found that the issue is more extensive
 than you've reported.

 Firstly, the same behaviour also exists when switching ''between'' grid
 and list views, regardless of the direction.
 Secondly, the behaviour isn't restricted to the Launcher… it also occurs
 in-game (in which case, flashback is to the in-game menu, including the
 game screen).

 However, another wrinkle exists in-game, depending on the graphics mode in
 use. On Mac OS X, OpenGL allows switching between views and displays this
 behaviour. On the other hand, graphics modes dependent on SDL only display
 in list view, and have the view buttons disabled, and thus avoid the
 issue.
 Note that the issue occurs in the Launcher with both OpenGL & SDL.

 Since switching views creates the same flashback as clicking the same
 view, and the objective here is to prevent an ugly flicker for an
 unnecessary action, I'd recommend your second option (to disable the
 appropriate view button).
