[MPlayer-users] [BUG] Switching between fs and windows breakage with XV, XMGA and X11.

[Jan Knutar]

Steps that reproduce this bug perfectly on my system:

mplayer -vo xmga anyfile.mpg (or -vo xv, exact same results. or .avi, 
doesn't matter)

Movie starts windowed. So far so good.
Press f. Movie goes fullscreen, so far so good.
Press f. Movie goes back to windowed. So far so good.
Move the window a few pixels or something. So far so good.

Press f. 

Window decorations disappear, window is resized to full screen 
resolution, BUT, the top left corner is placed approximately in the 
middle of the screen. That is, the upper left quadrant of the movie is 
visible on the lower left quadrant of my screen, with the rest of my 
screen being the desktop.

Illustration:

+--------+
|        |
|    MMMM|mmmm
|    MMMM|mmmm
|    MMMM|mmmm
+--------+
     mmmmmmmmm

Where M is the movie.


The behaviour is exactly the same with XV and XMGA, and even -vo x11.

Attached are mplayer-v-quiet-xv.log and mplayer-v-xv.log, in which I've 
started playback, cycled fullscreen, moved window, cycled fullscreen.

I'll paste the parts that I'm guessing might be relevant. Full output in 
the attached files.

Fun enough, the output looks no different for the second time I cycled 
fullscreen, when the window is positioned wrongly.

This was not reproducible with KDE's window manager.
