Razer Naga - Scroll wheel issue

Hi there, Since a few days ago I have a problem with the scroll wheel of my Naga : sometimes when I scroll in a webpage it doesn't scroll as it should, and then after a few more roll it does a scroll too much (as if it took the previous scroll and added it after). To me it seemed it happened after the last update from Razer Synapse, so I followed the article that said to uninstall Synapse and the mouse driver, reboot and reinstall (https://mysupport.razer.com/app/answers/detail/a_id/4135/). But nothing changed. Is it a problem that can occur ? It doesn't seem to be material at first glance, because the wheel is rolling pretty smoothly. Anyway, any input on this is welcome. Cheers !
