Comment 100 for bug 1690719

Well, cursor FPS could be a small problem and we could get used to it. Unfortunately, in some extrem cases the lag is so intense that it nearly freezes the mouse which leads to a crash, by turning the computer into a brick.

For example (so, be careful when opening those! depending on your configuration, it could be the last thing you will have done in this session... You've been warned), Chrome Experiment gives a tone of different mouse lag direct experience, with the 3D tag: https://experiments.withgoogle.com/chrome?tag=3D

On my computer in Chrome (with a Radeon HD 4770), this demo leads to a very slow mouse: https://demo.marpi.pl/archan/eutow/ and it's not linked with the amount of 3D to compute, because for example this demo: http://alteredqualia.com/three/examples/webgl_materials_skin.html is super fast and does not lead to mouse freeze.

This one leads to mouse freeze: http://www.zynaps.com/site/experiments/blox.html /!\ /!\ BE CAREFUL /!\ /!\

So, I'm back to X for now, but I hope that it will be corrected
