Interesting! What's your monitor like? Sometimes I suspect it's because of my 4K monitor (with 1.5x scaling), that's a lot of pixels to shuffle, especially if the rendering code/pipeline is not optimised[0]. Testing my setup with a 1080p/75hz monitor[1], it's crazy fast and responsive, but mouse acceleration curve (and scroll), not speed, is still weird. [0]See Ubuntu pushing for triple buffering for example, and other optimisation work on the past. [1]Apparently that causes huge speedup, as it affects frame scheduling, according to one GUADEC talk by a Mutter dev.
