Minus Front - Incomplete Shapes
This is an odd issue that is kind of hard to explain. Whenever I am using the minus front tool on some objects, the appearance doesn't end up quite right. For example, I subtracted these outlined text characters from a black background. The blue outlines show that they were subtracted correctly, but the white background showing through is cut off in the wrong spots?

Is GPU preview on? It sometimes leaves artifacts like this one you show. Try to switch to CPU and check again.
