Subject: [PATCH] Fix skin rendering issue entering dirbrowse

If the custom UI viewport (for displaying lists) changes size when entering dirbrowse, other viewports won't be correctly rendered and require a redraw.

The following is a minimal test case for an example SBS where (the specified background color for) the viewport at the top of the screen won't appear after the user has entered the (root menu of the) file or database browser:

%?if(%cs,=,1)<%VI(main)|%VI(other)>

%V(0,0,-,21,-)
%Vb(ededed)

%Vi(main,0,22,-,-,-)

%Vi(other,0,60,-,-,-)
