Default [Q] i9300 Touchkey problem

Hey I hope this is the right thread for my question, if not excuse me I'm new on being active on xda ^^
So my problem is that the Touchkeys on my Samsung Galaxy S III vibrate twice every time I touch them. I'm not sure if this is wanted or if it is a bug? But besides this little issue I'm loving Omnirom so another question would be if there is an application that can help this problem? ^^

Hopefully someone can help me thank you

PS: Sorry if my English is bad ^^
