Steps to reproduce:

Here is all described http://stackoverflow.com/questions/25995581/firefox-32-0-2-transform-issue Problem is transform -> rotateX between -0.5deg and 0.5deg, here is result http://jsfiddle.net/hdxoo9wy/1/
It is new bug, last version (i guess 31) was working correctly.


Actual results:

rotation between -0.5deg and 0.5deg gives random effect and when animation has this range - it shakes.


Expected results:

Best result would be working as in ff 31 version.

My guess goes to one of patches from bug 1008917.

34 and 35 are marked as affected. This fix has now been on m-c for 6 days. Do you think this can be uplifted to Beta and Aurora?

I'm going to go ahead and assume that the Beta approval should be on the patch for beta instead of this patch.
