The short answer is I think you must be doing something incorrectly.

Now for the longer story....

The wxwidgets device doesn't have the same popularity as say the cairo
and qt device drivers which provide alternative to wxwidgets which
also work on all platforms. However, we fully support the wxwidgets
device in the sense if users send in patches for wxwidgets that appear
also to work for us, we are happy to apply those patches.

That said, I don't think a wxwidgets patch will be necessary in this
case.

To prove that for yourself, please run

examples/c/x01c -dev wxwidgets -a 1.

and

examples/c/x01c -dev wxwidgets -a 2.

which produce wxwidgets results at two different aspect ratios.

Those results look good on my own Linux box (using the wxGC version of
that device by default). If they don't give you good looking results,
we should start comparing screenshots (off list).  However, I expect
they will give you good looking results in which case you should be
copying the broader aspects of how any of our standard examples (such
as the first one) are implemented so your own code starts producing
good looking results with wxwidgets as well.
