Description nereo 2015-11-18 14:34:57 PST
Steps to reproduce the problem:
1. create element which rotateY(#deg) every N seconds with transition (javascript timeout)
2. add a fixed element (outside the first element - not related to it) and apply a rotateY(#deg).
3. add any text and link to the html

What is the expected behavior?
fixed element should not move.
text should not be repainted

What went wrong?
the fixed element slighty move by 1-3px.
sometimes doesn't happen
sometime text became blurred when transition is occuring, like the whole document is being transformed

Did this work before? N/A
