Gnome Shell closes session with AMD Catalyst when Steam is open

As the title says, I have installed latest Catalyst package (kmod-catalyst-13.8-0.2.beta1.fc19.4.x86_64) and Steam from Spot repo, and when I open Steam gnome shell log outs from my current sessions and takes me to user selection screen again. Installing Catalyst from AMD binaries (with the needed perms patch) works ok. Am I the only one facing this problem?
