MSI GS65 Keyboard - FN keys send duplicated press & release signals

Hello,

Since some kernel versions, I would say 5.8.1 I'm experiencing a strange behavior, only with special keys function based (FN + BrighUp) where I receive 2 press and 2 release together. If I keep the key pressed I get an initial double press and a single release and then a loop of press release. Here is an example of showKeys output:

keycode 225 press
keycode 225 press
keycode 225 release
keycode 225 release
keycode 225 press
keycode 225 press
keycode 225 release
keycode 225 release
keycode 224 press
keycode 224 press
keycode 224 press
keycode 224 press
keycode 224 release
keycode 224 release

This happened with a MSI GS65 integrated laptop.
Thank you in advance and if you need any other information, please let me know.
BTW: This was done with pure TTY2 not under X.

Maybe this is not the right forum to do this, but I I don't know how to progress or what to search, is a very specific bug and behavior so any solution I tried over the internet is not helping at all.

I also add the raw scan-codes if that help:
