Give autohotkey a try instead. I was able to get rid of the Logitech software because of it.

I’ve found that’s because their mice will go to sleep and upon first waking they’ll briefly use an onboard profile before switching to the G Hub profile. This is also why it might feel like it has a different DPI briefly or different light settings for just a flash. The only way to fix this is to use their totally separate OnboardMemoryManager software to change the onboard settings while running G Hub. It solved this issue for me and it’s infuriating that this isn’t built into G Hub…

Try just directly using something like xmodmap. You want to interface with your OS as much as possible really, especially to get rid of the “need” for shitty software like this.
