Gnome crashes on 2 displays configuration

Hello,
I have following problem. I have notebook and I have external monitor connected via HDMI. I’ve tried all possibilities and found “separate X screens” as the best for my needs. But there is one thing that bothers me. When I login I can use special keyboard buttons (like volume or running calculator) without any problems. When I move mouse to second display, they still work. But as soon as I click mouse button on the second display, they stop working. Moreover if I try to go to Control Center/Keyboard or Control Centre/Mouse, whole gnome crashes and is restarted. There are also other consequences, like that keyboard layouts stop to be separated for each window and start to be global setting.

Does somebody have any idea, if and how I can fix it?
