From your Ubuntu logs:
winegstreamer warning: videoflip1: Internal GStreamer error: code not implemented. Please file a bug at https://gitlab.freedesktop.org/gstreamer/gstreamer/issues/new. winegstreamer warning: videoflip1: ../gst-libs/gst/video/gstvideofilter.c(296): gst_video_filter_transform (): /GstBin:bin0/GstVideoFlip:videoflip1: invalid video buffer received
Searching for this online seems to suggest that this would only happen with a really old version of gstreamer. Which gstreamer version/package do you use?
