    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Windows
            Status: NEW
          Severity: critical
          Priority: Normal

gst-launch-1.0 videotestsrc !
"video/x-raw,width=720,height=576,pixel-aspect-ratio=59/54" ! compositor !
"video/x-raw,width=786,height=576,pixel-aspect-ratio=1/1" ! fakesink

Works fine with videoscale, fails with compositor. Works with ORC_CODE=backup.
Works on Linux on the exactly same machine.
