I don't usually use the backdrop but I use Spaces all the time and I
can confirm what you are seeing with OS X 10.5.5 and Rev 3.0.0

It looks like a bug too me so I reckon you should file a report. I
thought a possible workaround might be to hide the backdrop when the
app was suspended and set it again on resume, but in my tests, the
suspend and resume messages are not being sent.
This would appear to be another bug which I will check out now and
report if it has not already been reported.
