User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150604162752
Steps to reproduce:
0. find a computer with a high-res (or retina) display, i used an 2014 MacBook Pro
1. open Firefox
2. open developer tools
3. check window.devicePixelRatio === 2
4. open the example from the attachment
5. move the mouse over the left or right eye
6. cross check with an 'low-res' display ( window.devicePixelRatio === 1)
Actual results:
- the browser did not fire an event with event.region set
Expected results:
- the browser fires the event when you move the pointer over the region highlighted

Small correction regarding the EXPECTED RESULTS section:
- the browser shall fire an event with event.region set when moving the pointer over an eye.

ensure that canvas.hitregions.enabled = true

Confirming purely based on the fact that we already have a bug on file from someone who noticed the automated test for this was failing on their hidpi machine (but assumed that was a problem with the test rather than the code).
Rik, do you have time to look into this?

Clear a needinfo that is pending on an inactive user.
Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
For more information, please visit auto_nag documentation.
