Segmentation fault while shrinking the X11 video output
Open a video with the plain X11 video output (not with XVideo!!). Once playback starts, shrink the video window quickly.
VLC dumps core with SIGSEGV. As far as I can tell at this point, some component upstream of the video output is still using the original (larger) picture sizes, even the buffer have shrunk.
The same problem occurs with the XCB output. The bug affects both VLC 0.9.9a and 1.0.0-pre2.
