Issue with mouse when 30bit color depth enabled for linux desktop

I have an issue when enabled 30bit color depth in xorg.conf, my mouse is moving but no reaction on click. My setup is openSUSE 13.1 x64 - gnome, Quadro 600 @ EIZO CS230 connected by displayport, nvidia driver 331.20. When i revert to 24bit, its OK. Is there any solution for this issue?
