Having the same issue with the ad banner. To my knowledge I haven't seen an ad that it doesn't happen with, the Microsoft Cloud one is particularly irritating due it's size though.
I usually have to scroll back to the top of the page to let the ad drop back into place then scroll down to carry on reading.
I am using Chrome 50.0.2661.89 on Nexus 6 running 6.0.1
Biting the hand that feeds IT
