Hello! I've done a bit of hacking through Compiz' sources, and I think I
found the reason for the first problem.
As far as I could follow the process, Compiz calls
updateWindowAttributes() on newly-created windows, with the stackingMode
argument set to CompStackingUpdateModeInitialMap. This function is
supposed to set the window's stacking, among other things. For instance,
at one point it runs:
if (stackingMode != CompStackingUpdateModeNone)
{
Bool aboveFs;
aboveFs = (stackingMode == CompStackingUpdateModeAboveFullscreen);
mask |= addWindowStackChanges (w, &xwc, findSiblingBelow (w, aboveFs));
}
Which raises the given window on top of everything if the stacking mode
is CompStackingUpdateModeAboveFullscreen. So newly-created windows are
placed below full-screen ones, because they're not mentioned in that
test. This might seem like a good idea, except that they're given focus
(don't know where), which means that input would go to a window that's
not visible (bad thing). Also, this is highly counter-intuitive (for
instance, starting Firefox's download manager with FF in full-screen
appears to be not working).
I changed the snippet above to contain
aboveFs = (stackingMode == CompStackingUpdateModeAboveFullscreen)
|| (stackingMode == CompStackingUpdateModeInitialMap);
and now the stacking is the way I'd expect it. Does anyone think it can
break something that way?

full-screen windows sometimes hide windows that should be above them
