Axis inputs "levelling out" intermittently

[sveppur]

Good afternoon, after recently upgrading the firmware on my Gunfighter Mk3 based MCG Pro stick (Mk2 BB), I've started noticing a weird behaviour from the axis input coming from the device.
I've played around with in JoyTester, performing circular motions with the joystick, and it's clearly visible there, how the input randomly becomes level for a short period of time, before going back to smooth readings.

What could be the reason for that happening? This issue affects all the axes (roll, pitch, thumbstick, brake lever).

A few hours of tinkering later I decided to see what will happen if I try flashing the firmware for the twist-equipped variant of my stick (_BB_Mk2_GunFighter_MCG_PRO_Twist_v2_16_5.vkb), and apparently that did the trick and the issue is not reproducible anymore.

That leads me to believe there might be something wrong with the firmware package for the regular MCG Pro (_BB_Mk2_GunFighter_MCG_PRO_v2_16_5.vkb)
