Possibly related to this, I have had reports from users of tvtime that
after running xine, tvtime only shows a black screen or does not show
video after is has been obscured. We rely on XV_AUTOPAINT_COLORKEY
being set in the version of tvtime currently deployed, so I thought it
might have something to do with this.
I thought that the value of this was always reset after the client
exits. As well, this problem does not seem reproducable with all
drivers, as I have many Xorg users that do not suffer from this.
