Solarmass I am having a tearing in Firefox and layers.acceleration.force-enabled setting doesn't work anymore. Another option is to enable Force Full Composition Pipline in the NVIDIA settings. How (and where) I should save a config file?
Solarmass According to https://wiki.archlinux.org/index.php/NVIDIA#NVIDIA_Settings I've saved it here /etc/X11/xorg.conf.d/20-nvidia.conf
