Screen lags with catalyst and kernel linux-3.10.6-2

Question

so I have been using arch for about a month now and it has been working fine. But since I installed linux-3.10.7-1 my screen started lagging.
when moving windows around the screen lags and when scrolling down in thunar it lags very much.
And I can't configure my monitors anymore in catalyst control center. same thing with the latest kernel: linux-3.10.9-1
so I downgraded to linux-3.10.6-2 for now and everything works fine.
catalyst version is catalyst 13.4-15, catalyst-utils 13.4-3
xorg version is xorg-server 1.13.4-1
I'm using openbox btw version = openbox 3.5.2-1
GPU = AMD Radeon HD 7850
Any idea what might cause this ?

Is the fglrx module loaded at all?
And what's the output of 'fglrxinfo'?
Most likely the fglrx module is incompatible with the recent kernel version.
A simple solution for this problem is using catalyst-hook.
THIS. You should do this because the kernel module in the catalyst package itself is compiled against the kernel Vi0L0 has on his/her system and there is no way to compile one for later kernels without installing the package Radioactiveman suggested.
