[css3-animations] animated transformed element looks very jaggy when absolute positioned
testcase - extracted from David Barons demo: http://dbaron.org/log/20110419-animations The top box is static (not animated), the spikes are smooth. The bottom box shows heavy jaggies on the spikes when animated, I slowed down the animation to show that the smoothing returns when the element 'settles'. (hmm, not sure if this is a style system or graphics bug) Hardware in use is a not-so-new 2.00 Ghz Core 2 Duo iMac with ATI,RadeonHD2400 graphics, OS X 10.6.7. Recent nightly builds.
Similar as previous test case, but without using position absolute for the spikes. The spikes remain smooth during the animation.
Seems like a layers issue. I don't see this on Linux.
