Question: Problem with spacecurve and anti-aliasing

I have Maple 13.02 on an Acer Aspire 5532 (64 bit) and there are some severe problems with plotting curves using spacecurve, DEplot, or any plotting method that plots curves. When the option is set for anti-aliasing, I get curves like this: and when anti-aliasing is turned off, the curves look like this: I have tested this computer with other graphics programs, and with Paintshop Pro, for instance, vector graphics curves reproduce perfectly well: I have never seen a problem like this, so I don't have any inkling of what might be wrong.
