I recently got a Dell AW3418DW that is set to 120Hz refresh and is showing that the monitor is operating in G-SYNC mode in the OSD info but, when I play, I don’t see any G-SYNC indicator, even if the entry inside the NVIDIA settings is checked: https://i.imgur.com/S7Bo0AE.png
I tried with CS:GO, TF2, DiRT Rally and Tropico 5. For the source games I’ve added “+gl_swaptear 0” as launch option like it was suggested in a thread on this forum, but nothing has changed.
The AW3418DW is the only monitor connected. I have installed mutter version 3.26.2-0ubuntu0.1 that should fix this bug.
I tried with both NVIDIA driver version 387.34 and 390.25.

I just tried with Xfce4 and I get the same exact result as Gnome Shell (no G-SYNC indicator).
