Ubuntu VM 12.04 x64 mozilla-inbound pgo test reftest https://treeherder.mozilla.org/logviewer.html#?job_id=7285474&repo=mozilla-inbound 00:34:31 INFO - REFTEST TEST-UNEXPECTED-FAIL | file:///builds/slave/test/build/tests/reftest/tests/layout/reftests/bugs/180085-2.html | image comparison (==), max difference: 27, number of differing pixels: 215
Both failures above are caused by the mouse being positioned over a button in the test causing it to render in a :hover state. While the -ref also has a button in the same position it seems it might be a timing issue whether you get a hover event or not before the snapshot is taken. Perhaps it would be a good idea to force the mouse to a default position before starting to run reftests, to avoid intermittent failures caused by the physical mouse position on a particular slave machine? (I'm pretty sure I've seen this type of failure before) On X11, we could use: # xdotool mousemove 0 0
Flags: needinfo?(dbaron)
I'd have thought we could use synthesizeMouse or similar to do that. (I even thought we already did, but I can't find the code.)
