I figure it's probably related to XRandR. Perhaps you can confirm that
by using XRandR to change the resolution of a real monitor running Ion3
and see whether the behavior is the same broken behavior or whether it
works there.

If you get the same broken behavior, you could look at
http://keithp.com/~keithp/talks/randr/randr/ which is an introduction to
XRandR. I didn't read through it, but I searched and found a statement
that may be relevant "Clients can select for RRScreenChange events to be
informed if certain properties of a screen have changed."

Let us know how this works out for you.
