           Summary: [bug] Multiple cursors appear when udev rules for
                    seats are applied
          Severity: normal
    Classification: Unclassified
                OS: All

            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

If one configures udev rules (/etc/udev/rules.d/weston.rules) on a pointer
device to use the seat functionality, then two pointers appear - one that is
bound to the seat and one which is not bound to the seat.

To re-create:
1. Set up udev rules to assign a pointer device to a seat.
2. Unplug and replug pointer device (or otherwise apply the new udev rules)
3. Launch Weston, move the pointer and observe two pointers on the display.
4. Modify the udev rule by commenting the entire rule out, unplug/replug
pointer device, now observe that the device controls the other pointer on the
screen.

Here's an example weston.rules file, just modify ID_VENDOR_ID and ID_MODEL_ID
for your device (use lsusb -vvv to find these values):
ENV{ID_VENDOR_ID}=="04d9",ENV{ID_MODEL_ID}=="0499",ENV{WL_SEAT}+="back0"
