mediafoundation: h264 encoder seg. fault

My pipeline is next:

gst-launch-1.0.exe videotestsrc ! "video/x-raw, width=1920, height=1088, framerate=60/1, format=RGBA" ! d3d11upload ! d3d11convert ! d3d11download ! mfh264device1enc bitrate=10240 ! h264parse ! matroskamux ! filesink location=123.mkv sync=1 -vv

after 30-60 seconds of encoding I have the next message:
