For some reason I have graphical issues with Skype. I had less of them 3 days ago and thought that if I reboot pc everything will work fine. But it didn't hit the mark. While reinstalling Skype I can see such picture right now:

I'm getting such error messages at console:

```
Gtk-Message: Failed to load module "overlay-scrollbar"
Gtk-Message: Failed to load module "unity-gtk-module"
Gtk-Message: Failed to load module "canberra-gtk-module"
