Three years or so. I don't do much full screen stuff but I have
played a few games that fullscreen. In any case I think the
behaviour is definitely not something we can accept.

For me with current trunk the fullscreen is just "usual display,
not expanded at all, as only thing on the screen". Regardless,
this code your patch deletes was added *to fix a bug* and you
cannot simply delete it because it happens to get in the way of
a different fix you want to make. You must come up with something
that fixes both problems.
