When I'm browsing my touchpad two finger scroll is "laggy". If I plug a usb mouse, the wheel scroll does not work. It happens with Goole Chrome (from AUR), Chromium and Firefox.

Everywhere else in the system wheels/touchpad scroll work fine.

Anyone experiencing this? Is there a way to fix this?

I'm running Arch Linux on a ASUS laptop (PU301L) with Gnome Shell 3.12.2.
I had to follow this in order to let the system correctly recognize my touchpad

After searching around I gave up. Now I'm on manjaro linux and my touchpad works fine, so I'm sure I've been missing something in the way

I'm sure you followed instructions at archilinux GDM wiki. I've had your problem and it seems the line

xmodmap -e "pointer =1 2 3 6 7 4 5" # set mouse buttons up correctly

in ~/.xprofile file was causing the problem. I commented that line and restarted and everything was fine again.
