Public bug reported:

On Ubuntu 16.04 with xserver-xorg-2:1.17.2-2, xvimagesink fails for
certain sizes of image. Originally seen when receiving a meeting screen
share in Pidgin, reproducible as follows:

$ gst-launch-1.0 -v videotestsrc  ! video/x-raw,width=905,height=720 !
xvimagesink

The problem is actually in glamor_xv.c, fixed by the following upstream patch:
