USB Raw device data screws with my screen on Ubuntu Bionic

I have a Saitek Pro Flight Panel which connects via usb to /dev/hidraw<n>.
It's opened with
f = open ("/dev..., O_RDWR |O_NOBLOCK)
, and it reads fine BUT some of the input data is also acting as mouse input.
A test program reading as fast as possible exhibits the problem, so it doesn't seem to be data overrun.
Any ideas?

Fixed it

By default, the Saitek Radio Panel was enabled as an input device for X. Following script fixes it.
id=`xinput list | grep -P "Saitek.*Panel" | grep -oP "id=\d+" | grep -oP "\d+"`
xinput --disable $id
by disabling the device to X.
This was verified (only) on Ubuntu 18.04.4.
