Random idea: it looks like you have compression enabled.  What if you
turn it off in the directory where the test runs?  Something like
btrfs property set <file> compression ... according to the
intergoogles.  (I have never used btrfs before 6 minutes ago but I
can't seem to repro this with basic settings in a loopback btrfs
filesystems).
