Yes, the small windows appears and disappears very fast (I'd say it
stay on the screen for about 0.25 seconds) but it still is noticeable.
It might depend on configuration options, I'm not sure, I'll test this
on other computers. Anyway, I have made a video so you can see with
your eyes:

http://mywing.altervista.org/mplayer/out.ogg

(note: in this video the small window stays on the screen for like
half a second or more, I think it depends on my system being a bit
slow when acquiring the video)

Moreover, I have noticed that when I use gmplayer with yuv suboption
autodetection (-vo gl) the video has a wrong size, while skipping
autodetection (-vo gl:yuv=2) gives the correct video size. Only
gmplayer shows this behaviour, mplayer works fine. You can see this
too on the video I have posted. Here are some more information about
this:

For some reason it seems to resize the window. If you need the video
I've used in this test you can find it here:

URL=$(mplayer -user-agent Quicktime -v -frames 0
http://movies.apple.com/movies/sony/aneducation/aneducation_720p.mov
2>/dev/null | grep Filename | awk '{print $6}' | tail -n 1);
file=$(echo $URL | sed -e 's/^.*\///'); mplayer -user-agent Quicktime
-dumpstream "$URL" -dumpfile "$file"

Thank you.
