I have reduced the page(s) I found this issue on to just a few divs. One has position:fixed and contains another that is moved by javascript and some other elements that seem to 'enhance' the problem. In my real life situation there where more elements, making matters even worse. There is a very significant difference in CPU usage depending on the 'position: fixed' style of the outer div. Remove it and the usage is moderate. Apply it and the CPU usages is much too high.
Reproducible: Always
Steps to Reproduce:
1.Open the page (including stylesheet and javascript) that I will attach
