Taskbar Thumbnail Previews Hanging
I included a screenshot below of the thing I'm referring to, because I've never been told what the actual name of it is.
Basically if Windows has been running a long time, the thumbnail previews for windows (from the taskbar) start to hang indefinitely until I click on them, or in an unfocused window. As you can imagine, this gets really annoying when I just move my cursor over an item in the taskbar, and one of these thumbnails pops up indefinitely, until I manage to make it go away manually.
