I'm using kwin as WM so should I fill a bug about it for this behavior?

Ok, so what is the solution so the sequence described above works
as I expected (go to full screen on which the mplayer window is)?

Probably using -geometry? If this is the recommended option should
I send patch to manual page, describing xineramascreen option behavior
wrt full screen and mplayer window position?

Thanks for the reply.
