Xv not visible after explicit draw

Hi,

first, sorry if this is the wrong list for such an issue, I didn't see
any obvious lists to ask developer questions for Xorg.

We're having a bug in GStreamer where an Xv-window (filled with video
continuously), for some drivers (examples are nvidia's closed-source
driver and ATI cards (any driver), but not the trident or open-source
nvidia driver), a window will not refresh properly after having had an
explicit draw (XFillRectangle). A simple test case (that is, if you have
GStreamer installed) is available in
http://bugzilla.gnome.org/show_bug.cgi?id=162504. Running it will show
video, pause for a few seconds and resume but the video will not show on
some drivers after the resume. Moving the window around fixes it.

Is this a driver bug or an application bug? Assuming it's an application
bug, what should I do after XFillRectangle() to make XvShmPutImage()
succeed?

TIA,

Ronald
