Note that under X with evdev and synaptics, the mouse cursor rendering is handled in the SIGIO handler, thus interrupting anything else the server currently does. So even if the server is flat out busy, the mouse cursor will update.

Under X with the libinput driver, we currently don't use the SIGIO handlers. So if the server is busy rendering, the cursor stalls (https://bugs.freedesktop.org/show_bug.cgi?id=92720). I suspect all reproducers above would've used the libinput driver to reproduce this under X.
