Check your figure renderer in each case with get(gcf, 'Renderer'). My guess

is that one uses OpenGL and the other does not; there may be a conflict

between OpenGL and MATLAB on your machine. Verify this diagnosis with

sections 4 through 7 of:

and take a look at sections 8 and 9 for possible solution methods.

Also, if you're using MATLAB 6.1 (R12.1) or earlier, see:
