Proposed earlier this summer for GNOME's Mutter was the idea of triple buffering the desktop when the GPU is running behind in order to ideally cause that extra load to ramp up the GPU clock frequencies in order to in turn get back on track with rendering the desktop on-time. A third version of that work is now brewing albeit too late to see with the imminent GNOME 3.38.0 release...
