Actually let's reassign this to weston. And this is not a bug, this is a
feature request.
The Wayland wl_output interface already provides the means to discover the
output geometry, in particular
the physical_width and physical_height, as well as the current mode width and
height of the output.
Expected result:
???????????????????????????????????????????????????????????
The mouse pointer should adapt its dimension to the DPI of the output
where it's displayed. But how?
What physical size should be the cursor? When you're watching the tv
from 3 metres then the cursor physical size should be at least few centimeters.
On the other hand, on a small screen tablet (with mouse attached), the cursor
would be tiny
let's say 6milimeters across?
It seems nobody really knows how this is even expected to work. Because not only
the DPI matters, but the viewing distance aswell.
Actual result:
The physical mouse pointer dimension is different on two ouptuts.
The mouse pointer pixel dimension stays the same on any output regardless of
the DPI or other factors.
Tested on:
drm: libdrm-2.4.42-4-g41fc2cc
mesa: snb-magic-14773-g4154ac0
wayland: 8f1386fb504c298f703501dc409ddbd14e1ae036
weston: e7144fd175d1d68b91aa0cec7ab63381b79385a9
cairo: 1.11.2

Title:
Mouse cursors should be vector graphics
Status in “dmz-cursor-theme” package in Ubuntu:
Confirmed
Status in “weston” package in Ubuntu:
Incomplete
Status in “xorg-server” package in Ubuntu:
Confirmed
Bug description:
In a modern system the mouse cursors should be some kind of scalable
vector graphics.
This will become increasingly important with upcoming new high resolution
screen panels that allows for higher pixel density.
Other systems are already moving in this direction with vector graphics for
mouse cursors.
Currently mouse cursors often come in several variants such as
Chameleon-White-Large, Chameleon-White-Regular, and Chameleon-White-Small.
Vector graphics could unify this to just one variant that is scalable to
arbitrary size and provide more flexibility.
This will also be more important as Ubuntu expands to other devices such as
on 10-inch tablets and 52-inch TVs.
