Slowly growing memory usage with H264 decoding

I have a problem with this command:
gst-launch-1.0 filesrc location="file.mp4" ! qtdemux ! avdec_h264 !
GStreamer version is 1.16.1 from Ubuntu 19.10 distribution (also reproduced
The memory usage of the gst-launch process is continuously growing while
the file is being played. The rate of growth is very slow at ~1MB/7min.
If I replace xvimagesink with fakesink, the memory grows much faster until
the file is successfully decoded. Steadily from ~140MB to ~170MB for 4 hour
This problem persists with playbin and decodebin elements.
If I replace source H264 video with the one encoded in VP9, the problem
goes away. Any other H264 video exhibits this problem.
Anyone else experienced this? What can I do to diagnose the issue better?
Thanks you in advance,
