Hi,
My Spark, Mini1, Mini2, Air, Air2 did and do the same sometimes, loosing or gaining height or just indicating that.
It all depends (how else...) how the airflow is going through the drone and along the barometric sensor.
As i analyse all my flights and others i see this often, but flying at height far away you do not see this actually happen; i mean flying at 80 meters and uncontrolled to 77....i do no see that with eye ball mark 1.
And in the logs, out of VPS range it it hard to check and know if the height did change or it was just indicating loosing height.
See my video, on a windy day....flying low fast backwards. Baro height indicate 12 meter to almost zero while in the log VPS height only lost 3 meters.
Flying forward starting low, at the end UP command.., on the backwards leg no DOWN down command!
Do i care....well, knowing this i never fly fast and low when my drone is out my normal sight, so i can correct height if needed.Flying far away from me at heights in normal mode, well few meters up or down doesn`t matter too much.
Is it good? nah, but i can live with this behaviour.
cheers
JJB
