This is particularly annoying for owners of 144Hz/120Hz/240Hz displays. [Test Case] 0. Find a monitor or laptop with a high refresh rate (120Hz or more), noting NOT to trust gnome-control-center or xrandr because an unrelated bug in mutter may cause those to report 120Hz even on 60Hz displays. Make sure the advertised hardware specs show the display is a high frame rate. 1. Edit /etc/environment and add: CLUTTER_SHOW_FPS=1 2. Reboot. 3. Open a terminal window and run: journalctl -f | grep FPS 4. In a new window run 'glxgears' or some other OpenGL benchmark. 5. Verify the terminal window from step 4 shows high FPS values coming from the journalctl log that match the hardware spec, and are much higher than 60. [Regression Potential] Medium to low. This patch has been used upstream and in Ubuntu 19.04 for some months already without any issues. Although minor syntactical changes had to be made to avoid conflicts when backporting it from mutter 3.32 to mutter 3.30.
