On occasion when I am scrolling through search results the results freeze and they shake from side to side. No I am not drinking too much coffee!
That sounds more like a video driver issue. I've never seen the behavior. But just in case you might want to enable logging and upload your logs.
A screencast would probably be more helpful than logs in this instance.
OK but never done that. How do you screencast?
What is the best screencast software and are there free ones that I can download or is this built into windows 10?
I use Jing, which is free: https://www.techsmith.com/jing.html
A list of some other tools is here: https://wiki.logos.com/Screenshot
Apparently there is a built-in way in Windows 10, but I have never used it: http://betanews.com/2015/07/19/windows-10-secret-screen-recording-tool/
I have the movie ready it is 63mg but I can't save it at an attachment. It is a Mp4 file.
Tried to load a shorter version 11 seconds. I keep getting this message when I try to attach the video. The connection was reset.
