** Description changed: - Monitor is set to 144hz, but on Wayland it visually fails to go above - 60Hz. I have confirmed the monitor is running at 144Hz during the - Wayland session, and that is also the setting in the Settings control - panel. + [Impact] - Using the additional NVidia drivers installed using the Ubuntu software - control panel. + Gnome Shell redraws at 60Hz at most, regardless of the hardware refresh + rate, and regardless of the current display mode.
