If I go through fotos, core using raises 100%. Reproducible: Always Steps to Reproduce: 1.Go to http://icpc.baylor.edu/dmt/tour.htm 2. 3. Actual Results: CPU core using raises 50-100% Expected Results: Core using should be reasonable (in IE it's negligible)
I am seeing increased CPU, but not sure what deal is.
"Animation" seems to be causing this; because when I set image.animation_mode to once or to none, the CPU usage suddenly goes down. Something is invisibly animating which is consuming all CPU time.
