I am running Xubuntu 12.04 with xscreensaver version 5.15 (as it comes
from Synaptic), and I noticed that while the screensaver is running
and the screen is locked, when I type something or move the mouse to
unlock the screen, the input window remains behind the image - or so
it appears: the mouse only shows up within the bounds of where the
window would be, but it is not visible on the screen.

The screensaver I am using is GLSlideShow.

This only happens on my home desktop. This did not happen on this
machine when I was running Ubuntu 10.10 about a month ago.

this also doesn't help):

fglrx version is 2:8.960-0ubuntu1.

Should I file this as a bug? I've also found a way to crash the X
server in this config, although it is tricky.

Jamie (xscreensaver's author) says it's the ATI fglrx driver.

I put an NVidia video card in my machine and the problem is gone.

I also filed a bug at AMD/ATI, but the response I got from their
customer support was not promising (a non-Linux person responded).

You pretty much have to give the Devil his due. nVidia has a pretty good
track record of support for Linux, even if it's a closed source binary.
I use nothing else. Ric
