I have not seen that behaviour in windows Chrome desktop, but have seen it on the surface pro.
I also often get that happening on the iPad using iOS Safari. My thinking was originally that it was a touch device problem, but now you have posted about it, maybe it is not.
Never bothered reporting it, as it does not always happen.
Sorry for not updating you all here- this was discussed in one of our private spaces. Both the screen jumping issue and the latest reply/original post broken links are related to a known issue with Chrome 61. Unfortunately since it's an issue with Chrome, Jive is waiting for Google to release an update to fix. We can try to roll back our Chrome version or use another browser in the meantime.
