ONYKS

Hello! At the moment i am using TT saphira mouse and i have a little problem with it. Keys at the side (mouse3 and mouse4) while using are displaying an red arrows on the bottom of screen, which shows their default action (previous and next site) even if its not their actual action (when i am for example playing games and that keys are binded, they anyway shows that arrows). Can someone explain me how can i disable displaying that? Thank you so much in advance
