MATLAB: patches disappear in various circumstances when faceAlpha is not 1

I am using 64-bit matlab r2010a on Windows 7 (this may be relevant if this is an incomprehensible rendering error)

this is apparently a strange mistake that appears when the latex text interpreter

set(0, 'DefaultTextInterpreter', 'Latex');

this code will create a blue square with a black frame and a legend outside the axes

cla reset;
patch ([0.5 0.5 0.75 0.75 0.5], [0.5 0.75 0.75 0.5 0.5], 'b', 'FaceAlpha',1); 
xlim([0 1]); 
ylim([0 1])
legend ('blah', 'Location', 'bestOutside')

If I change the code so that the patch has an opaque alpha value,

cla reset;
patch ([0.5 0.5 0.75 0.75 0.5], [0.5 0.75 0.75 0.5 0.5], 'b', 'FaceAlpha',0.5); 
xlim([0 1]); 
ylim([0 1]);
legend ('blah', 'Location', 'bestOutside')

I get an empty black box instead of a full one, and the axes are correctly modified to place the legend outside, but without the legend.
