This problem with display2D:false Maxima has with a lot of functions.
It is a general problem of lineardisplay. We had some time ago a longer
discussion about this problem under the topic "Linear display not correct?".

the problem with 2D display, or else start my

(%i2) laplace('diff(a(t), t), t, s);
(%o2) s * 'laplace(a(t), t, s ) - a(0)
I recall someone else on the mailing list complaining
