It's just a zorder issue. If I flip the zorder in the example it seems
to work:

gst-launch-1.0 -v videotestsrc ! video/x-raw,format=AYUV,width=640,height=480 ! shapewipe position=0.5 name=shape ! compositor sink_0::zorder=3 sink_1::zorder=2 name=mixer ! videoconvert ! autovideosink     filesrc location=mask.png ! typefind ! decodebin ! videoconvert ! videoscale ! queue ! shape.mask_sink    videotestsrc pattern=snow ! video/x-raw,format=AYUV,width=640,height=480 ! queue ! mixer.
