--Something's happening there!!

Confirmed on an nVidia-based laptop. Will post the output later when I turn it on, if relevant.

If using the nouveau driver it seems to be fixable by installing nouveau-dri.
I met this while trying to get fallback mode enabled. In gnome-shell all windows are either blue or transparent, so I unistalled nouveau-dri.

duplicate of  FS#29202 ... I did not see this, and now I managed to solve the problem by simply reverting Cheese. No need to log out or restart, worked immediately. Awesome!

I just needed to do this:
sudo pacman -U /var/cache/pacman/pkg/[cheese-olderversion].pkg.tar.xz
...and I got my system settings back :)

How do I close a task?

Just wait for a developer to do that. We do not have the rights to.

Allright thanks a lot
