So, I took a shot at the kde bugtracker (https://bugs.kde.org/show_bug.cgi?id=304469) and Martin Lubking there was most helpful, if I understand it correctly his conclusion was that ToEE was trying to use an old way of establishing a full-screen window, failing and only using a canvas which kwin can't or don't manage.
Frankly, what's written in that bug report doesn't make a lot of sense to me. Just so I'm sure I'm understanding this correctly, the application window in http://bugs.winehq.org/attachment.cgi?id=41229 is supposed to be 1280x1024, but actually stays something like 800x600. That e.g. _NET_WM_STATE_FULLSCREEN wouldn't be set in that case isn't all that surprising, it doesn't get set if the resize failed.
One thing I did notice in that screenshot is that the size is actually 1279x1019 instead of 1280x1024. Is that because you cropped the screenshot, or does fglrx actually give you that resolution if you ask for 1280x1024? Either way, if it works with the free driver it's probably not worth worrying too much about.
